Reebok's ZigTech Flow sneaker is like an energy drink for your feet. This technologically advanced shoe features ZigTech engineering which allows key leg muscles to do less, so that you can do more. The PU sockliner adds comfort and support, while the lightweight upper remains breathable. It is designed to absorb energy on impact and reduce vibration creating a soft, quieter, more efficient ride that requires less muscle activation.At heel strike the 'zig's' both shear and compress, absorbing energy and minimizing energy-draining vibration. That energy is stored and returned to the athlete in a quiet, smooth, spring-like effect.Our Easy Tone Reebok also recommend  this Reebok Easytone Reeinspire Lux Synthetic Leather Women Shoes Whi Shoes t
