Positive
  • The thing I love about this great shoe is that it can be used for so many different runs from tempo runs, long runs and track workouts too. These have to be one of the most comfortable shoes I have ever ran in. From the moment I took them out I knew these were going to be great. I highly recommend this shoe.
  • At present I've been suffering with knee problems whilst running but these shoes are so great and have not broken down at all despite the fact I have had them for a while and taken them out on quite a few runs. I often have trouble finding shoes that last but these have held up so well and my knees have been doing really well so far. They also look great! If you have knee problems like myself or have trouble finding a lasting shoe I would say go ahead. You won't be disappointed.
  • I find this shoe great for speed training and I think they will be great even for a half marathon. However the sizing does feel a little small compared other well known brands but as long as you're aware it isn't so bad. I love the design and think this is a really versatile shoe.
  • I haven't had these shoes for long but I have to say that they are incredible. I've only taken them out on a few runs so far but I've enjoyed every one. They are so good that my times have improved no end! The only slight negative is that they are a little smaller than your average shoe. I had mine professionally fitted and had to get a size larger than I normally would. Great cushioning and makes for a nice natural run.
  • This shoe is so light and responsive that I can't imagine running in anything else. I trained for and ran a marathon in them and they performed brilliantly. I have ran many marathons in different shoes but these have surpassed them all and my feet were not sore this time after running such a long distance.
  • I really love everything about this shoe except for the sizing. I had to get a larger size because the 8 felt way too small but apart from the sizing this is a really comfortable shoe. Great for all types of runs from tempo runs or just running for pleasure. I was also surprised I didn't even have to spend ages breaking these in. They feel so light for a highly cushioned shoe and are super responsive. I'm really pleased with my purchase.
  • These really are excellent running shoes but I have to say that the mesh has ripped on the sides so many times now. I thought that the first time this could just be a one-off but I've owned several pairs and this continues to be a problem. I love the shoe and they feel so great on runs but I wish they were more durable.
  • This shoe has impressed me. I'm used to running shoes with a 12mm drop so I expected to find the Freedom ISO's 4mm drop a problem but I was pleasantly surprised. Finally a shoe that lives up to it's promises. It feels so lightweight, the heels never slip, great cushioning and they feel secure. I would recommend ordering a size up or maybe a half size and then you shouldn't have a problem.
  • I had always been loyal to Nike but after feeling let down but some of their latest models I decided to shop for other brands. I found Saucony! Many running shoes are too wide for me but the Freedoms worked out great. I usually run about 5-6 races a year and they have been perfect for training and competitions. Good support on the heel and grip on the sole. I just wish they came in other color options!
  • I really want to give these shoes more praise because they are almost perfect but the sizing is a problem. My feet felt so restricted around the toes that I could see the outline of my toes through the shoe. This was pretty painful so going for a long run in them felt out of the question. It's a shame because I really liked these and I can't order a size up as they go no higher than a size 15. I would say order a larger size than you would usually wear and just be aware of tightness in the toe box.
  • I will say one thing: Watch the sizing on this shoe. They are different from other Saucony series. I would definitely go a size up. I suffer with pain in my hips and have found these shoes are really helping with this. They feel light and tight and are suitable for road running.
  • These feel light and comfortable but I don't think they offer my arch the support I need. This is the only downside to these shoes.
  • I'm one of those people who buys new running shoes all the time so have tried many different brands but after using these for a couple of runs I think I'm sold. I love how light and responsive they are and they are great for road running. I guess the only downside is that they're maybe too light!
  • This shoe has really impressed me. I'm used to running shoes with a 12mm drop so I expected to find the Freedom ISO's 4mm drop a problem but I was pleasantly surprised. Finally a shoe that lives up to it's promises. It feels so lightweight, the heels never slip, great cushioning and they feel secure. I would recommend ordering a size up or maybe a half size and then you shouldn't have a problem.

  • I've tried so many different brands of running shoes but these are by far my favourite. I did have to buy one size bigger than I would usually wear but they do fit well. Im not the most experienced runner but I have already bought another pair I love them so much. Other shoes used to hurt my feet but not these.
  • I truly love these shoes but to be careful if you are buying them for running as you will need to go one size larger. These really are the most comfortable shoes I have ever ran in but make sure you size up.
  • This shoe is great. My feet felt comfortable and secure but the shoe not too tight so no rubbing. I like the look of these and they provide suitable cushioning throughout.
  • I can honestly say these shoes are worth it. They are without a doubt the best ones I have ever owned and after trying so many others thats saying something. They feel well supported and secure yet breathable and light at the same time. Almost like a sock. I will definitely repurchase after these have worn out. I sometimes experience pain in my back when I walk or run and these shoes have really helped with this.
  • hese shoes are so comfortable. My feet are pretty narrow and for me the lower drop really helped me out. I run regularly and would say I ran 600+ in these and they remained just as cushioned as the day I first wore them. For me they are a little pricey so I'm not sure if I will be able to buy another pair.
  • I'm an experienced runner and have had these shoes for a while. They have to be the best running shoe I have ever tried. They're lightweight and the cushioning is perfect. Maybe the lightweight feel won't work for everyone but for me it's great. I've probably ran around 200 miles in these shoes and the sole looks like it's been barely touched. Really helps with leg soreness.
  • I purchased these shoes after a recommendation and although I have worn Saucony's for running before I have to say I'm so impressed with this shoe. I couldn't wait to get out for my first run in them and I was not disappointed. I recently ran an 8k race and could feel the difference coppered to my previous running shoes. They feel very light and cushioned and I even feel I wanted to run faster! I will be buying these again.
  • The fit on these shoes is excellent and molds to your foot. I'm a person who buys lots of running shoes and I find these to be super light and responsive without compromising the cushioning and support runners need.
Negative
  • I'd heard so much about this shoe I was really excited to try it but when I did I was a little disappointed. It certainly feels lightweight and responsive but the cushioning is lacking something. It almost felt like it wasn't going to hold up and my feet really didn't feel supported enough. I think it's probably good for speed runs and maybe race days. I do think it's a good shoe but I wouldn't use it every day and it's also a little pricey. It's not really the shoe for me but I can see why it is so popular.
  • After I'd taken these out on a few runs my heel was hurting but I think it's because the drop is a little lower than my last shoes. Once I had gotten used to them though it was fine. These are the first Saucony shoes I've owned and I know they won't be the last.
  • I found these shoes so uncomfortable. The cushioning doesn't even feel like its there and I was so disappointed when my feet hurt. Also the sizing isn't accurate and they feel like a size smaller than the marked size.
  • These shoes started to come apart after I had only completed a few runs in them. I actually have running shoes that are less expensive and have lasted longer. I reached out to Saucony to try and get a replacement (I didn't feel they should be falling apart so soon) and initially they agreed to send me another pair but I haven't heard anything from them since and this was a few weeks ago. Not the best customer service.
  • I really wanted to like this shoe but it was too small and I would have to buy a bigger size to make them fit properly I ended up returning mine.
  • I so wanted these shoes to be great for me but I was surprised to find there is barely any cushioning. I really liked the appearance but thats about it. I have bought so many running shoes from Saucony but I felt they offered little to no support for me. They are lightweight and look really attractive but I think I probably need a little more support now I'm getting a little older. Perhaps better suited to younger runners.
  • I think these shoes are probably great for straight running but you really can't use it for anything else. I wanted something that would be good for cross fit also. I found my feet kept slipping away off the sole. It's a pity as they are really comfortable but the lack of support along the sides doesn't work for me and I'm worried about injury.

Outsole
Outsole

Outsole

The outsole of the shoe is a clear crystal-rubber Tri-Flex material that is lighter and designed to be more flexible and durable than traditional carbon rubber. Similar to the Saucony Triumph ISO 2, it serves multiple purposes, providing better traction and flexibility while maintaining its durability. While the transparency of the outsole may lead runners to doubt its durability, other reviews show that after as much as 300 miles the rubber did not show significant wear. The thickness of the outsole is consistent from the heel to the head of the foot and provides runners with a consistent feel throughout each stride. Its durable surface provides a layer of protection to the shoe’s midsole, thus increasing its life and justifying the cost.
Midsole
Midsole

Midsole

The Saucony Freedom ISO is Saucony’s first shoe that contains the EVERUN Continuous Cushioning technology throughout the entire midsole. Saucony has implemented this technology in their shoes before the Freedom ISO, just not to this extent. The midsole is entirely constructed using thermoplastic polyurethane, or TPU. This material’s lightweight design is longer lasting and offers more resistance to common causes of footwear damage such as splitting, abrasions, oil, and other chemicals. The full-length EVERUN technology throughout the midsole is similar to Adidas’ Boost Technology, except Saucony’s offers more firmness. As a result, the shoe possesses a particular bounce or response that translates to a faster and smoother ride.
Upper
Upper

Upper

The Saucony Freedom ISO’s upper is composed of thin, perforated mesh which is soft, stretchy and breathable. Its design is combined with a stretchy bootie and a tongue that is sewn directly to the midsole of the shoe and includes a rigid surface providing grip for the laces. The upper is less structured than that of other Saucony ISO models, yet it still offers great support. The forefoot of the shoe is wider than other models, but with the added width plus the stretchy material, the shoe accommodates itself to different volumes of feet. Altogether, the minimal design of the upper offers a flexible and tight fit without any pressure points, which translates to an even hold.
Weight
Weight

Weight

Coming in at 9 ounces for the men’s model and 8.1 ounces for the women’s model, the Saucony Freedom ISO is one of the lighter running shoes on the market. This is because the multiple lightweight components the shoe is comprised of. From the new ISO-Fit technology and EVERUN cushioning system to the thin layer of mesh that makes the upper, many of the areas that make up the shoe are designed and engineered to provide the shoe with lightweight characteristics. The one area where runners and reviewers found to make up most of the shoe’s weight was the midsole. The EVERUN material made out of TPU is slightly more dense than what most running shoes are made of. At 9 ounces, however, many runners were left satisfied with the shoe’s weight.
Breathability
Breathability

Breathability

The Saucony Freedom ISO’s upper construction offers great breathability. This can be attributed to the mesh layer that makes up the upper of the shoe. However, with great breathability comes greater exposure to the elements. Runners and other reviewers have claimed that in colder and wet conditions their feet were left too exposed and that the shoe was prone to allowing water in via the thin and breathable layer of mesh. In calm and dry conditions, the shoe allows the foot to breathe comfortably during the workout.
Comfort
Comfort

Comfort

Much of the Saucony Freedom ISO’s comfortability comes from the uniform level of the EVERUN cushioned midsole. Its 4-millimeter drop from heel to forefoot provides the foot with a stable and even cushioned surface. The EVERUN midsole, as mentioned earlier in the review, is firm and gives the runner a nice ‘bounce’ after every strike. The shoe’s laces pull firmly, not tightly, against the walls of the shoe while the tongue naturally and comfortably disappears into the final fit. The construction of this shoe, unified throughout, rids the foot of uncomfortable pressure points and secures the foot with a sock-like fit.
Style
Style

Style

The Saucony Freedom ISO has a sleek and colorful design to it. The shoe possesses aesthetic features, including its bright multi-colored outsole and various colorful colorways. Its thin and flexible structure give it a contemporary look. And while the Freedom ISO is classified as a running shoe, reviewers have said the shoe wears well outside of training within their everyday life.
Durability
Durability

Durability

The Saucony Freedom ISO’s reputation is built largely because of its durability. The crystal-rubber outsole, mentioned earlier, provides most of the durability and seems to withstand normal wear and tear and offers a layer of protection to the midsole from damage. The midsole will remain intact longer than previous EVA midsoles found in other models. In other words, the EVERUN will maintain its cushioning, energy return and bouncy properties long into the shoe’s life. Paired together, the crystal Tri-flex rubber and the EVERUN midsole ensures the runner with a shoe that will hold up longer than others.
Protection
Protection

Protection

The Saucony Freedom ISO has some areas that protect the shoe very well along with some that leave the foot exposed in certain conditions. For starters, the soft and flexible qualities of the crystal-rubber outsole efficiently protect the midsole and foot from repeated impact. Further, a toe bumper at the forefoot of the outsole adds further protection. As the bottom construction of the shoe offers great protection, the upper mesh leaves the feet vulnerable to elements due to its increased breathability. Reviewers have complained that when they have worn the shoe during rain or snow, moisture easily penetrates.
Responsiveness
Responsiveness

Responsiveness

The Saucony Freedom ISO was designed to enhance responsiveness through its new midsole technology. After composing the midsole of nearly 100% EVERUN cushioning material, something Saucony has never done before, runners feel more of a response (more bounce) after each time their feet strike the surface. The quality of the material Saucony uses is designed specifically to return to its original form quicker than shoes lacking the EVERUN cushioning. As a result, the shoe has a unique ride quality reviewers describe as snappy rather than mushy. Overall, the Freedom ISO has balanced itself well with cushion, increased responsiveness, support, and feel.
Support
Support

Support

The Saucony Freedom ISO does a good job in providing support through the bottom of the shoe with its cushioned midsole and added layer of crystal-rubber on the outsole. With the ISO-Fit technology making up the upper part of the shoe, the tongue and outside walls also provide sufficient support to the runner. Where the Freedom ISO lacks support is towards the rearfoot and the heal. The shoe’s low heel cup decreases the support given to the runner’s ankles. In addition, some reviewers thought the thin mesh material that makes up the upper shoe does not offer as much support as they would like.
Terrain
Terrain

Terrain

The Saucony Freedom ISO is designed to withstand long and slow distance road-running. Its outsole, made up of the single piece of Tri-Flex crystal-rubber, provides structure underneath the foot while its narrow and uniform depth from heel to toe give runners a consistent landing zone. In addition, the increased durability of the outsole is capable of resisting wear and tear against rough surfaces. Reviewers praised the close to the ground feel of the Freedom ISO as it does not compromise its protection against elements. While the Freedom ISO is best used for slow runs, a few reviewers complimented the shoe for its performance during speed training. Under wet conditions, however, the rubber outsole has shown runners a tendency to become slippery, resulting in less traction.
Price
Price

Price

One pair of the Saucony Freedom ISO will run you anywhere from $140-$160 depending on the retailer. Compared to its competitors, the Freedom ISO is one of the more expensive models on the market. This shoe will thin your wallet slightly. However, it pays for itself with its durability and multi-purpose use.
Traction
Traction

Traction

The Saucony Freedom ISO’s outsole does not offer the best grip for runners on wet or icy roads due to the crystal-rubber not being 'sticky' enough to hold on. Reviewers who tested the shoe in the snow or on wet roads explained the shoe could not grip the road well enough during their run and the new rubber is considerably worse than the carbon rubber that was used for previous Saucony shoes. In comparison to harsh conditions, the shoe performs well on groomed trails, treadmills and dry tracks and roads. The chevron-style pattern on the outsole adds surface area to the bottom of the shoe and improves the shoe’s flexibility.
Flexibility
Flexibility

Flexibility

With the thin layer of mesh that makes up the upper section of the Saucony Freedom ISO, runners are given a flexible fit that accommodates different foot lengths and width. As mentioned above, the chevron-pattern outsole increases the shoe’s flexibility. The ISO-Fit material of the upper section is a thin layer of perforated mesh, translating into a natural and highly flexible ride.
Stability
Stability

Stability

The Saucony Freedom ISO provides a full ground contact which increases the stability of the shoe by way of its outsole. Unfortunately, that may be the only part of the shoe that contributes to its stability. The shoe’s flexible and unstructured upper made from ISO-Fit, coupled with a lower than usual heel cup often translates to a less stable ride. Also, many reviewers thought that the unstable rear and forefoot sections of the shoe raised minor concerns. However, the shoe seems to be more temperature stable than other products. This is because the TPU foam that makes up the shoe’s midsole is far more durable and maintains its firmness and responsiveness at lower temperatures.
Drop
Drop

Drop

The Saucony Freedom ISO features a 19mm heel and a 15mm forefoot, which comes out to a 4mm heel to toe drop. Within the industry, the average heel-offset is roughly 9-12mm. Runners may need time to adjust to the lower ratio and might experience soreness or another injury after first using the shoe. However, those issues are expected to dissipate with time and further use of the shoe. The smaller heel-offset length places the Freedom ISO within within the same ballpark as other high performance shoes. With that, the shoe may be more suitable for regular workouts rather than racing.

Bottom Line
Bottom Line

Bottom Line

The Saucony Freedom ISO is a product meant to make a statement to the industry. It incorporates brand new concepts within the midsole and pairs that with its distinct outsole and upper mesh design. By doing so, the shoes introduce themselves as a unique and energetic ride. Implementing the EVERUN midsole and ISO-Fit system give the shoe its secure, sock-like fit and comfortable fit. The various colorways and modern design and structure make it an attractive shoe that can be worn not just for workouts, but for social activities as well. The price is rather steep, but for advanced technology, one can expect to spend the extra money. This shoe defies standard classifications. It is so versatile that critics and reviewers cannot place it into a singular category. If you are a fan of Saucony products, or have never tried one before and are willing to spend the money, then the Saucony Freedom ISO is the shoe for you.
