Make every session count with these women's Free TR 6 trainers from Nike, workout essentials design to break through performance barriers. Built with a lightweight yet durable mesh upper for breathability and support where you need it most, asymmetric Flywire cables lock down the forefoot for optimum support and adaptability every minute of your training. The Free's latest innovation comes in the form of auxetic foam to the outsole, which expands upon movement, spreading out impact and pressure equally, delivering a more natural, barefoot-like feel so you can smash through training goals free from restrictions. Keep them fresh with Crep Protect Spray (Product Code: 110853).. Material: Textile Upper/Synthetic Sole
