UltraBOOST Uncaged Shoes

Ultra-responsive shoes with cage-free, integrated support.

A turbocharger for your feet. The ultra-responsive boost™ in these men's running shoes absorbs the force from your footstrike to release it at push-off for an energized ride. A simplified design combines a cage-free adidas Primeknit upper with integrated support that hugs your foot through the gait cycle.
