Picture the best run you’ve ever had. Now picture it lighter, faster and with more energy. The all-new boost™ midsole on these women’s shoes gives you an amazingly soft and bouncy feel that isn’t over-cushioned, so you can run right past your current PB before you even knew you passed it. The techfit™ upper has a seamless, sock-like fit that stretches and flexes as you run, and a TPU cage gives the foot stability. With TORSION® SYSTEM support in the midfoot and a stable heel counter.
