The definition of comfort may as well be Ultraboost. This version of the adidas shoes takes the energy-returning feel they're known for and turns it up a notch. BOOST in the midsole is wrapped in Stretchweb to amplify that walking-on-a-trampoline feeling, and an adidas PRIMEKNIT upper hugs the foot. No running required. This pair is geared toward day-to-day wear. Brand new in box. Price is firm.
