?Scientific Design ?C The ball of foot cushions is designed to meet the shape of human??s foot by having a comfortable little ridge which keeps the ball of your feet in position and prevents your foot from sliding forward. And the super soft gel pads reduce the pressure on the toe and effectively relieve ball of foot pain. ?Premium Raw Materials ?C The metatarsal pads are made of durable, soft, and safe medical-grade silicone gel, which makes them elastic and flexible. So, the pads will not be deformed after being used for a long time. The outer-layer (black and beige) has the function of absorbing sweat. ?Easy to use ?C Clean the shoes first, then simply peel off the adhesive tape from the pad, and stick the pads to the sole of the shoes. Once you place them into your shoes, they will safely stick to your shoes. ?One Size Fits Most ?C These shoe inserts fit most feet sizes. Do not stick to your skin and do not give yourself unpleasant smell. ?100% Customer Satisfaction Guarantee ?C This package comes in one color: beige (6 pairs). If you (our esteemed customers) feel like you don??t see the value of our products, we will replace them or give you a full and no-questions asked refund.
