The left shoe feels like it has a lot more cushioning. The right shoe hurts my foot a lot! Fast forward in 2 months. The right leg is still killing me. Almost as if 2 shoes were made by different manufacturers. . After only a few months of using this shoe, some of the rubber is separating from the shoe. I work in the medical field and would love to love these shoes but the right shoes still kill me and the time to buy new shoes. Really sad to pay 170.00 for a shoe that hurts so much and the rubber is falling apart.
