Nike Free sneakers

The Nike Free TR 8 Women's Gym/HIIT/Cross Training Shoe has a stronger heel than ever before, plus extra cushioning that hugs and contains your foot. The sole is still unbelievably flexible, offering a natural, lightweight feel and lateral support through every rep. The heel is flatter than it was in previous models, which creates a wider surface area and greater stability for exercises like squats. An added layer of material over the heel gives it more durability and structure. Very gently used indoors only
