Altra Intuition 4.5 Review Facts
Watch Video Review

Altra presents the Intuition/Instinct 4.5, a slight modification to the previously released Altra Intuition/Instinct 4.0. The Intuition/Instinct 4.5 is a zero drop running shoe that is said to provide its wearer a more natural stride. It is being touted as a shoe with extensive applicability. An “all-purpose,” shoe is how it is being regarded. The running shoe is presented with dual names because Altra prides itself on making sure that each model of their running shoes has specific features to account for the anatomical differences in men and women. The Intuition, for instance, is the women’s running shoe, while Instinct is the men’s running shoe. The difference between the male and female models is important but slight, so for the majority of the following review, they will be discussed as a singular entity.

Below you will read a summary of them:

Positive
  • I was a huge fan of the 1.5 and have ran them into the ground. All of the others were less than satisfactory but these are right there with the 1.5. They are actually a bit longer than the 1.5, which is great for my toes. They have moderate padding and the zero drop is great.
  • These shoes are great for my martial arts training. I ended up taking the insoles out and they fit to size. They have a great heel grip and stop grab. Not as good for my over-pronation than my 4.0 but the width has helped my toes breath and move around better. The zero drop in really great , these are the only style shoe I have worn that doesn't give me joint and back pain.
  • I am so happy that I was able to find my size with a generous amount of space for warmer socks and my toes to wiggle around. I wear a size 12 in womens and they are usually difficult to find anywhere else.
  • These shoes are so durable. I wear them every day and stand and walk for hours and they have held up like tanks. I also have neuroma and I have a hard time with shoes these however, they have proven to be the best shoes for me. I am also able to use these at the gym and I have no pain. Great shoe Altra.
  • These shoes are the best in toe box space and I have never worn a more comfortable shoe.
  • All Altra's are super small so I always buy a size bigger. These are no exception. These have great cushioning and the toe box is so wide and comfy as always. These are the only brand I prefer for all my gym and daily needs.
  • I have been buying Altras since I found out about them and they have always been the best. I love the roomy toe box. I am able to sue these all day at work, where I stand and walk over 10,000 steps and these are always comfort. I am never suffering from pain or fatigue at the end of the day. This model specifically is the best one out there for sure.
  • These were perfectly fit to size for me. I usually wear the 2.5 but they were discontinued and these have held up to that standard. I am able to take these for my long walks and they give me all the support I need with no pain.
  • I was really impressed with the arch support in these shoes. I have abnormally high arches and these give me the right amount all over.
  • Altra always has such amazing toe room and these shoes in particular have epic support in the arches.
  • I have to have a shoe with a wide toe area because of my neuroma. These shoes are just what I was looking for. They are beyond the comfort level that I was expecting and they are really durable. I also am glad they come in great colors, I may need to order another pair.
  • For the price, these shoes are uncomparable. They are super comfortable, durable and the toe box is epic! I have never found a better shoe for the price.
  • The cushion on impact is out of this world. The zero drop makes everything all into place without creating an imbalance. They are wide open in the toe box and this has helped me in both of my marathons. I recommend these shoes to any one needing a great shoe with tons of support and agility.
  • I use these for my running and for my work shoes. They run a bit small so I ordered a size up and they fit like they are supposed to. These shoes hold up to everything. I am super happy with these.
  • THE PRICE IS RIGHT! These shoes are nothing but a win! They have carried me over 3 continents and multiple terrain and have never caused any pain or damage to my feet. The toe box is wide, they are super sturdy and the arch support is killer. BUY THESE SHOES! You will not regret it.
  • I have wide toes and thee shoes always give me the space I need without losing stability. They have relieved me of all my excruciating toe pain I used to get when I wore other shoes. I want to hug these and think them every time I take them off.
  • I actually really love Altras. These however, they are wide in the heel and I cannot get them to tighten enough. I'm hoping they don't get worse as the padding wears down.
  • Out of all the Altras I have bought over the years, these are by far the best ones. THey are stellar in comfort and design and I highly recommend them.
  • These shoes stretched out my achilles, which has really helped me with my ficiilitis. I have never been able to wear shoes without orthotics until I found these I am now pain free and happy. They have just the right amount of cushioning and the zero drop is crucial to helping with the fitiicitis issue. I swear by the intuition model!
  • I was a Torin fan for years and I was hesitant to change. However, after using these for a few weeks, I am forever changed. THese shoes have outdone anything I could have ever imagined. They are a little less cushy but they are still just as comfortable. The mesh allows so much air to run though the shoe and my feet stay nice and fresh. I am so very happy with these shoes.
  • I was recommended these by my doctor; he was on point with these. They have a nice round toe box that is wide open, which gives me enough space to wiggle my toe without the shoe sliding around. They are by far the most comfort I have ever had in a shoe and I will never look back as long as Altra continues to make shoes like this.
  • I have been waiting for them to replicate my favorite shoe, the 1.5, and they did it. This is the best design that Altra has ever made. I ordered a size larger as I always do and they ft great. They have so much support and comfort. It just cannot be beat.
  • I did not have to break these in, they were perfect out of the box. Do you know how hard it is to find shoes like that? I have some jacked up feet and they are always in pain. Working and running with these shoes has changed my life. I feel like a brand new person.
  • Took these out and went on a 3 mile walk instantly. I have a history of severe joint and foot pain but not with these. I was waiting for it to settle in when I was done, nope. I am over the moon that these are an actual thing. Comfort, style, stability, it is all there.
  • These shoes are so breathable and light. I was thinking they might not last due to how light they seemed. I was completely wrong, these have handled so much carnage from me and I will be buying again. These have to be the best dang shoes I have ever worn. I am a huge fan and highly recommend.
Negative
  • I find it had to order Altras due to size issues. This model was by far the closest to size for me. I really use my runners a lot and these have not held up at all, comparably. They are stiffer in the toe area and slip in the heel while being narrow in the arch. They started collapsing after a couple wears and the sides are all scrunched up. They are also heavier than I ever remember an Altras to be.
  • One shoe was visibly a different size although they were marked the same and the padding in the ankle was over done. They kept rubbing and it made them very uncomfortable.
  • These shoes feel like boats on my feet. They are heavy and they make my ankles and legs fatigue after I run. These have significantly changed my running time for the worst. I am not compatible with these shoes at all.
  • These shoes eat my socks. It has to be the most annoying thing ever. The way the shoes fit doesn't allow you to wear socks properly. I love the look of the shoe and they are comfortable, but the sock eating is a deal breaker for me.
  • I could not get used to the low heel on these. I mean I have heard nothing but raves on the zero-drop technology but it just isn't for me; way too low for my use. .

Outsole
Outsole

Outsole

The outsole of the running shoe incorporates the FootPod design. This means that the shape of the outsole better aligns with the contours of the foot. It features a decoupled heel as well. The outsole has to it a fair amount of rigidity.
Midsole
Midsole

Midsole

The midsole of the running shoe is essentially an amalgamation of Altra’s A-bound technology and the more commonly used EVA foam. Most in the running community are familiar with EVA foam, but for some the perks of A-bound cushioning may need elucidation. A-bound is a patented technology from Altra. This cushioning extends from the toe to the heel. It evenly distributes its own weight across the length of the running shoe in an effort to facilitate better running technique, one in which fewer impact energies are channeled into the foot.
Upper
Upper

Upper

The upper of the Altra Intuition/Instinct 4.5 differs from its predecessors because it is made from a soft mesh-like textile. This material allows the upper to better enwrap the foot and, because it is a little bit more malleable, better move in accordance with the runner’s foot. This mesh, it should be noted, is not exceptionally elastic. This is good as too stretchy a mesh can result in the upper feeling too slack. The upper also incorporates an inner sleeve. The ankle-collar reaches higher here than on previous incarnations of Altra Intuition/Instinct. The running shoe adopts a traditional lacing system, and the eyelets have added stitching.
Weight
Weight

Weight

The Altra Instinct is, in the average men’s shoe size, approximately 9.8 ounces in weight. For the Intuition, in the average women’s shoe size, that weight is closer to 7.2 ounces. The insole seems to add a considerable amount of weight to the shoe. The insole, itself, weighs 1.3 ounces which are about two times the weight of a traditional insole. Many runners have noted, though, that this excess weight is not quite felt when the running shoe is in use. Some attribute this almost lightweight feel to the flexibility of the running shoe.
Breathability
Breathability

Breathability

The upper of the Altra Intuition/Instinct 4.5 features a porous fabric that allows for the sufficient flow of air into the running shoe. Runners have deemed it as being well ventilated and a great deal more so than its predecessors. The toe box of the running shoe, however, was not considered to be very well ventilated, and this, for some will be a disappointment.
Comfort
Comfort

Comfort

The toe box of the Altra Intuition/Instinct 4.5 is one that grants the wearer sufficient room for toe splay. This interior does not provide room in one dimension. No, both in terms of height and weight, it can be considered spacious. This allows the running shoe to better serve those with wider feet. The extra room will also do well to serve those with Morton’s neuroma, bunions or other ailments. Those with narrow ankles may deem the heel lose, and be turned off by the running shoe’s extra volume. The cushioning is more or less evenly dispersed about the running shoe, but a select few have criticized it for being too rigid. The tongue is adequately cushioned. There is considerable padding about the heel collar. The interior bootie, or sock liner, is made from a sponge-like material that some have described as being similar in texture to that of a yoga mat. The midsole is quite snug, and a traditional lacing system allows the wearer to get the most comfortable fit. The designers of the Altra Intuition/Instinct 4.5 also took into consideration customers’ complaints about the toe bumper on previous models. This time around, they’ve presented a much softer toe bumper that is sure to alleviate many of the pains, such as abrasions, that afflicted wearers of previous models.

The women’s version of the shoe runs a bit small, so interested buyers are encouraged to try a half-size up. The women’s version of the shoe is equipped with more cushioning than the men’s. This is because the designers of this running shoe wished to better address the minute differences between men and women’s feet. To add a bit of clarity here, a woman will typically have a more narrow heel than a man, but a larger ball and ball girth than man. In her research study, biomechanist Kate Bednarski, M.A. found evidence to suggest that women who run competitively have higher arches than women who don’t. Altra made sure to pay attention and respect to these anatomical differences when constructing this shoe, and it shows.
Style
Style

Style

The Intuition/Instinct 4.5 is of a shape more in keeping with the Altra Intuition/Instinct 1.5 and 4. Unlike those releases after the Altra Intuition/Instinct 1.5, and leading up to the Altra Intuition/Instinct 4, the Altra Intuition/Instinct 4.5 does not have an overly aggressive curvature. It has what many runners consider to be a more streamlined look than its predecessors as well. It employs a stack height of 25 millimeters. The tongue of the shoe has less foam inside of it, allowing it to eschew the rotund look of the tongues of earlier models. The upper also incorporates a neat color-blocked design that is sure to turn heads. Coupled with this are 3D printed directional lines as well as a dye-sublimated print pattern. The Intuition is available in the following colors: black, predominately pink with some black and predominantly light blue with some gray. For the Instinct, a different set of color options are presented. They are as follows: black, predominantly blue with some lime green and predominantly red with a bit of black.
Durability
Durability

Durability

It has been claimed that because the outsole of the Altra Intuition/Instinct 4.5 has to it a considerable thickness, it is well equipped to deal with the stressors of the road without breaking down. This claim has some merit but it may not be wholly true. Some runners claim to have noticed ripping between the midsole and outsole of the shoe after extended use. Another runner said that, in conjunction with the usual heel wear, he noticed a scraping way of the outer patterns of the forefoot after 12 miles of use.
Protection
Protection

Protection

There is a protective patch at the forefront of the running shoe that acts as a toe bumper. Some runners have expressed their doubts about the effectiveness of this bumper, though. The outsole of the running shoe provides very little protection against those items one might encounter when traversing a rugged trail.
Responsiveness
Responsiveness

Responsiveness

Some runners did note that, after extended use, they did register some forefoot pains, but these were slight. The amount of propulsion, or spring, lent to toe-off did leave a lot to be desired.
The Altra Intuition/Instinct 4.5 is best suited for those runners who employ a more midfoot dependent stride. Heel strikers will find the responsivity to be lacking considerably. These shoes are equipped to handle 20-mile stints rather than multiple kilometer treks. Those seeking an Altra shoe with more propulsive qualities might want to consider looking at the Altra Escalante.
Support
Support

Support

The running shoe employs a neutral arch support. The supportive insole has a thickness of about 6 millimeters. The expansive coverage of this insole allows it to better bolster areas of the sole of the feet that are typically without the shoe’s adequate support. The insole is also removable so those who need to insert orthotics can easily make the necessary accommodations.
Terrain
Terrain

Terrain

The running shoe is designed to function best on traditional roadways. Some runners were even satisfied when using this shoe in the gym, citing its lock-down as one of its principal benefits. Those who have tested the shoes on rugged trail ways noted that the ride was a considerably unstable one. The shoes may fair better on smoother trails, but it would be a bit ill-advised to recommend these shoes for such an application. The shoe may also struggle to optimally serve its runner at high speeds, therefore it would be ill-advised to use these shoes for race day.
Price
Price

Price

The Altra Intuition/Instinct 4.5 occupies a pretty attractive price range as it is considerably less expensive than other competing models.
Traction
Traction

Traction

The wide foundational platform on which the running shoe rests allows it to excel during climbs. Runners have found it allowed for successful descents, as well. The outsole performed well on wet surfaces and gravel filled pathways.
Flexibility
Flexibility

Flexibility

Incorporated into the outsole of the shoe are Inner Flex grooves. The Inner Flex grooves form a unique cross hatch pattern. The positioning of the flex grooves is anatomically sound. They adorn the outsole at the specific locations where the foot is want to bend. While they don’t have any great springiness to them, they do grant the runner a more natural stride. The recoil on a taut portion of the shoe is also a very slow one. This is ideal for ascending an incline or performing a slow-paced linear exercise.
Stability
Stability

Stability

In terms of stability, the shoe will best serve those with wider feet and ankles. Those runners with more narrow features can definitely still enjoy the wear but may need to make adjustments to the lacing before feeling stable. The high-reaching ankle collar grants the wearer greater stability. Several overlays present in the heel and forefoot give more security to the upper. Still, a spacious collar opening can become a source of instability for runners with a smaller build and this should not be overlooked. An inner sleeve grants the runner a greater midfoot hold.
Drop
Drop

Drop

The Altra Intuition/Instinct 4.5 has the unusual characteristic of sporting a zero drop. This design is supposed to grant runners a more natural gait and body position. The health benefits of this are many. The typical running shoe has a drop of 12 millimeters, give or take, so one can clearly see that these shoes, with their zero drop construction, are the outliers. Some runners depending on their amount of experience with shoes of this design may find it to be too flat.

Bottom Line
Bottom Line

Bottom Line

The Altra Intuition/Instinct 4.5 is a fairly priced running shoe with adequate stability, and a level of flexibility that betrays its heft. It makes for some pretty comfortable footwear to wear on light treks across roadways. It also functions well on inclines and declines. Some have even touted its reliability as a piece of gym-centered footwear. It can not be considered the perfect all-purpose running shoe because of its limited functionality on those more rugged trails. Still though, those things that those Altra Intuition/Instinct 4.5 gets right are done very well. It has what some may consider too-large of a heel and too-spacious an interior, but other than that, it does well to accommodate runners of varying body types.
