ULTRABOOST 21 PRIMEBLUE SHOES
ULTRABOOST 21, SAY HELLO TO INCREDIBLE ENERGY RETURN.
The definition of best never rests. When we dropped the first adidas Ultraboosts, they were the best running shoes we ever made. With each new update, we raise the bar. Now you get the cushioning you didn't know you needed with the energy return you've always wanted. This version features 6% more Boost capsules and a supportive adidas Primeknit upper. It gives you an extra push of energy in each step that comes from the Linear Energy Push system, which offers forefoot and midfoot support.

HIGHLIGHTS
PRIMEBLUE
This product is made with Primeblue, a high-performance recycled material made in part with Parley Ocean Plastic. 50% of the upper is textile, 92% of the textile is Primeblue yarn. No virgin polyester.

INTRODUCING ADIDAS LEP

FORGED ADIDAS PRIMEKNIT

ULTRABOOST
