adidas UltraBoost 21 Men's Running Shoes

• adidas Primeknit+ upper wraps the foot for targeted support, comfort and lightweight performance
• 6% more BOOST capsules than the ULTRABOOST 20 deliveries incredible energy return: the more energy you give, the more you get
• PRIMEBLUE upper is made for high-performance, recycled material, reflecting the adidas commitment to sustainability
• LEP torsion system in the midsole provides less flex in the forefoot for a more responsive stride

The ultimate expression of comfort and responsiveness.

The ULTRABOOST is the flagship of innovation within adidas, where each shoe is designed to be superior to its predecessor. ULTRABOOST 21 takes all the aesthetic ingredients that were part of the original shoes' DNA and fuses them with the latest technology to create a shoe with incredible comfort, support and energy return.

At first glance the Primeknit upper looks to make its return; however, this version utilises a more precise knit designed to give enhanced support and movement as well as being constructed from PRIMEBLUE, a recycled material of at least 50% Parley Ocean Plastic.

Elsewhere the TPU midfoot cage makes a return, and the updated BOOST midsole delivers time and time again with its signature soft foam and explosive energy return. On the grip front, the shoe is complete with a Continental rubber outsole for maximum traction across a range of surfaces.

So whether it's rainy Berlin, a crisp early morning by the Thames, or the idyllic foliage of Central Park that sits as the backdrop to your training, the UltraBoost 21 will always push you through that barrier that separates you from casual runners. Forever.
