    The Ultra Boost upper abandons the use of a regular tongue and collar design, and instead adopts a full bootie construction, which means that the walls of the rearfoot opening run broken. To make it easier for the foot to slide in, the collar fabrics are elasticated, coupled with an exaggerated Achilles area.

    The collar of the shoe is a little low, and the material inside was a little slippery at first. Tinker with the laces, and the shoe fits fine, however I can't help but feel that if the collar sat a touch higher, or the laces were slightly further back, Adidas would really have the best shoe on the market.

    I think there's room for improvement on this shoe because I can definitely see the benefits of going with a Boost long-form shoe. Something that will take you on those long, long runs, Marathon, maybe even beyond. There's just some elements [that] I think need a little fixing.

    The primeknit upper hugs your foot without any constraint. Your feet have a true sense of freedom, comfort and loads of breathability. The bouncy boost midsole offers plenty spring under your foot when running.The excessive wear on the outsoles though is disappointing to me.

    So far my longest run in the ultra boost has been 10 miles, but I don't see any reason why this shoe could not take me through a marathon or longer. If you like a secure feeling in your shoes, you should love how the primeknit molds to your foot like a second sock. Fans of premium cushion running shoes should definitely consider the adidas ultra boost when they are next looking for shoes.

    The new Ultra Boost looks good, is super light, feels good, gives you a lot of room, provides tons of cushion (perhaps too much in the long run), and allows for a natural-feeling heel-to-toe transition if you’re a heel-striker like me.

    Let’s just get it out of the way, this shoe is hot. I don’t mean hot as it,“yah they’re kinda pretty” I mean hot as in if you saw this shoe in a bar you would conjure up the courage to walk up to it, buy it a drink, flip it’s hair, tell it it’s the most interesting shoe you’ve ever met and risk the wrath of your wife who’s sitting in the corner watching this whole ordeal.

    This is a very versatile shoe, being fast in a 5k and comfortable over longer distances. The full benefits of the Ultra Boost foam will be felt by heavier runners and those with a more pronounced heel strike although it still feels light a responsive to a lighter runner like myself.

    At first I was a bit skeptical as to whether shoes made by knitted material can provide enough support and is strong enough to withstand daily runs.

Updates to Ultra Boost

Adidas hypes the Adidas Ultra Boost as “the best running shoe ever.” Such bold claim is primarily anchored on its innovative and revolutionary Boost midsole foam that is not only very cushioned, but also superbly responsive. The superior responsiveness of the shoe is supported by The Three Stripes’ assertion that it is 20% more responsive than any of the Boost models.

More than just the extremely responsive and cushioned midsole, the Ultra Boost boasts of ¾ one-piece Primeknit upper that hugs the foot in comfort. A Stretch Web outsole delivers more than adequate grip on the road and light trail while the newly designed split heel counter prevents slippage in this area and eases pressure off of the Achilles.

Ultra Boost size and fit

The fit of the Ultra Boost is unbelievably comfortable. Besides the generous padding all throughout, runners with average dimensions in their feet will love the adequate space in the heel, the secured midfoot, and the wide toe box. Available widths are the standard D for the men’s and B for the women’s. Sizing is on cue in this shoe as well. Sizes are from 6 to 15 for the men’s and 5 to 12 for the women’s.


The outsole literally resembles the form of a as it is rightfully called the Stretch Web. Like a real web that adjusts to the spider’s movement, Adidas’ proprietary outsole rubber adapts and stretches to maximize the power of every stride. Additionally, it offers flexibility and an element of natural running.


The midsole is undoubtedly the domain of 3,000 blown TPU energy capsules. According to Adidas, the Ultra Boost has an astounding 20% more of these shock-absorbing and responsive TPU pellets than any of the other Boost models. It means that there are 20% more pellets that lock themselves together to take on the impact of every stride and convert the same impact for a truly responsive ride. Another technology in the midsole is the Torsion System or the plastic bridge insert that offers torsional stability and enhanced transition without adding weight.


An engineered mesh that has precise stretch points that hugs the foot like a second skin. Adidas’ digital knitting process uses synthetic yarn that produces extremely breathable, supportive, and lightweight one-piece upper. Altogether, the engineered mesh and Primeknit material, adapt to the runner’s foot while offering maximum comfort and support. Inside the shoe is a lightweight sockliner that enhances the plush comfort even more. One very noticeable part of the upper is the sleek and catchy heel counter that cradles the foot in support and prevents untoward movement in this area. Comfort and stability are offered by this innovative heel structure.
