Adidas Adizero Boston Boost 5
The Adidas Adizero Boston Boost 5 is the fifth revision to this lightweight trainer/racer. Slightly lighter, wider, and featuring a thinner midsole than its predecessor, this shoe is for those who like taking their run on the open road, but also like a appreciate cushioning in the heel. Named for the Boston Marathon, this shoe is meant for speed and distance.
Runners liked the overall fit of the shoe and had few complaints about its performance. The Boost foam technology gives the shoe a springy feel which can really be felt at fast speeds. Consider this shoe if you’re in the market for a marathon trainer or just a comfortable and durable running shoe.
- Responsive Boost technology
- The outsole offers a solid grip
- Lightweight, comfortable build
- Soft and breathable mesh upper
- Great shoe for short and long distances
- Torsion System in the midfoot offers greater stability
- Good traction on slippery and wet surfaces
- Runs small, will need to size up
- A rather high drop
- The upper mesh was irritating against bare skin for some
- These are my springy running shoes, super light, the cushion is perfect, I have two pairs of these. Remember to look at sizing up. My feet are wide and the fit is nice and supportive.
- I have narrow feet so I went for these, the fit is so exact, they really give nice return, done a lot of miles in 5 months with these, very comfy.
- These took me some time to get used to running in but I can say that having recently used them for a full marathon that these shoes are outstanding. Light, nicely flexible, very well placed cushion and good rugged durability.
- When I touched the continental tread I knew these will be durable, these are shoes that run as far as you choose, even marathons, the tread works in all weathers and is very durable, nice cushioing and a great spring or energy return
- No need to break these in I used them for long distance right away and they are good, done two half marathons in these and use them weekly for running, outstanding shoe
- The platform rubber has been super durable, I run 50 miles each week, I’m hitting very challenging surfaces and the shoe can really stand up to the punishment. These are perfect for extensive long distance racing and running. Love the arch support.
- The spring feels great in these, the shoe does not weigh much so I feel like I’m flying along in these because they really are designed to improve running, I can feel it.
- These are my best speed shoe at such a light weight, the energy return is so good, though the shoe is light the support is built in comfortably for long runs.
- Did fifty miles in these in two weeks, these are super for spring or return to get the body moving along faster. The cushioning has a good feel, breath-ability feels standard and the traction is so impressive.
- Runs much to narrow, the uppers feel a bit abrasive inside, the lace up system is bizarre, the holes are so small and the shoelaces wear out so fast.
- I didn’t like the high drop in these, it just does not suit the way I run for my feet, the shoes let shock travel up through my ankles up to my knees.
- Within two weeks the tip of the shoe came away from the mesh and made these unusable, very disappointed, these shoes are not well built.
- Changed sizing and went through a lot of hassles, the shoe is far too narrow and even trying to break these in and get fit through stretching the shoe did not work.
The use of two different types of rubber in the outsole makes the heel much more aggressive and durable, providing more bounce and flexibility. This translates into a smooth heel-to-toe transition with exceptional surface control.
The foam is resistant to different temperatures, keeping them from becoming stiff in cold weather or spongy on hot days. The Boost material provides great shock absorption and rebound. A lot of runners commented on the lightness of the shoe and springy feeling that allowed them to lift their foot with ease. A removable EVA sockliner adds a bit more cushioning as well.
Located in the midfoot area of the midsole is what Adidas calls their Torsion System. This “system” is a wishbone shaped thermoplastic protective plate which allows the forefoot and midfoot to move independently. This motion lessens the strain on the arch of the foot.
The Torsion System also provides good arch support and helps with the runner’s stride through the gait cycle. Runners prone to plantar fasciitis said the Torsion System helped ease the pain in the arch of their foot which allowed them to continue to run.
Synthetic suede overlays on the sides of the shoe are stitched to the upper and work in conjunction with the lacing system to support the foot and keep it in place. A suede toe guard gives protection and support to the front of the shoe. Heavier material and padding in the back of the shoe keeps the heel aligned with the rest of the foot.
The tongue is sufficiently padded to relieve the pressure of the laces across the top of the foot. Peek under the tongue on the left shoe and you will find a “Boston Runs As One” reminder from the Boston bombings.
A wide toe box helps keep fresh air circulating around the feet. Runners complimented the breathability of this shoe stating their feet were only slightly warm, even after long runs. Despite the wide holes in the upper, there were no reports of small pebbles or dust getting inside the shoe.
Some forefoot runners felt the cushioning in the heel was a bit of a waste, but heel strikers appreciated the design. Less cushioning in the forefoot means better ground feel which many runners prefer. Forefoot and heel strikers will both benefit from the midsole's shock absorbing features.
The shoe's moisture-wicking tendencies keep the foot cool and dry and prevent hotspots and chafing. Most runners enjoyed the feeling of the upper, but a few sockless runners said the material irritated their bare skin after extended runs.
The side overlays and laces work together to customize the fit of the shoe when the laces are pulled tight. The supplied EVA sockliner is removable and the shoe can accommodate most insoles and customized orthotics.
Adidas running shoes tend to come in standard dark colors, but this is not the case with the Boston Boost 5. Men have some bright color options to include red, bright green, and bright yellow. Women can choose from hot pink and orange in addition to the standard black, blue, and gray.
This rubber is very resilient and can withstand not only wet and dry pavement, but also wide temperature fluctuations. This means the shoe will give a consistent performance no matter how hot or how cold the pavement.
This technology also helps the Adidas Adizero Boston Boost 5 maintain its integrity longer. In addition, the shoe incorporates AdiWear foam rubber which is abrasion-resistant and also quite durable. The upper material also adds durability to the shoe despite its open mesh design.
The suede toe guard offers some protection from thumps and bumps that may be encountered while trail running, but it is not meant to be a rock guard. Stick to the roads with these shoes and they will serve you well.
In spite of the cushioning, the forefoot area of the shoe still manages good ground feel which allows for confident and quick push-offs. Most runners enjoyed the fast feel of the shoe and said it made them want to run even faster.
This feature prevents excessive strain on the arch and allows the midfoot to roll gently forward after ground contact. The aggressive outsole also ensures a powerful and confident run. There were no reports of slipping on painted surfaces or very wet surfaces.
The AdiWear rubber in the forefoot area is thin enough to allow runners to feel the ground but still provides some cushioning. The shoe also does well on wet surfaces and can adapt to hot and cold temperatures.
The upper mesh material also helps make the shoe flexible while retaining structure. A slightly stiff heel and flexible forefoot allow a natural feeling with every step. Many runners commented on this feel which provided a very smooth ride.
The midsole is not overly thick (16mm in the forefoot) which keeps the runner low to the ground compared to other cushioned running shoes. The shoe's forefoot area is fairly wide and makes a good platform for stable landings and quick push-offs. A low heel-to-toe offset also contributes to the shoe's stability. The aggressive tread also ensures a solid landing and lift.
