The Maya is a Mary Jane with a Stridarc rocker sole. Stridarc is a highly engineered outsole that rocks thanks to a rigid bi-fit board embedded in the outsole. The bi-fit board works with the contoured sole to gently but firmly cradle the foot as it moves through every step,mitigating the impact reactions and eliminating the thousands of tiny joint and muscle compensations that cause fatigue.Additional InfoSADMERC,PDAC,Mid Heel
