Cinfa Farmalastic Feet Plantar Pad Footwear Closed Footwear Size Medium N° 39-41 is a product developed by Cinfa laboratories for its brand Farmalastic. It is made of polyamide and elastane fabric, with a silicone gel filling. It has been designed to act as a plantar pad when the natural part of the foot is worn, injured or causes pain when walking. It helps to minimise hardness in the area, protects the skin and improves pressure distribution. It should be avoided if the area has open wounds.
