The Reebok EasyTone Reeinspire fitness trainer can help tone some of your hard earned leg muscles by using pockets of air in the shoe. EasyTone activates certain muscles in your legs more than a traditional walking shoe. The air pockets also absorb energy when you walk to help create resistance, requiring more energy in every step. They have a SmoothFit breathable mesh upper, padded ankle collar for extra comfort, female specific footbed with removable insole, shock absorbing DMX technology gait-balancing midsole and a durable non-marking rubber traction outsole.
