adidas Womens Ultraboost 21

Description

Updating one of the most famous names in running was never going to be easy, but the adidas Women’s Ultraboost 21 Ash Pearl/Ftwr White/Halo Ivory builds on prototype after prototype to provide incredible energy return.
The adidas Women’s Ultraboost 21 generates a linear energy push system with every step. What this means is that forefoot and midfoot stiffness increases through the stride to provide an extra energy boost at the end of your step.

The temperature independent ultraboost midsole provides huge levels of energy return even as your feet heat up through the run, where some shoes would get softer and less responsive.

A stretchweb outsole made from super grippy continental rubber moves with your footstrike to give a smoother and more flexible ride.

The Primeknit+ upper is highly breathable and moulds to your unique foot shape for a comfortable feel and personalised fit.
