Ultra-thin gel strips to protect your heels from chafing on Aliexpress. The beauty of shoes is rarely matched by their comfort. By the time a new pair is worn, they will have lost their original look, but they will have had time to chafe your feet. These silicone inserts act as a protective function for the heel and allow you to walk freely and without pain, even in brand new shoes. The strip is flexible and is glued to the back of any shoes or boots. Thus, between the foot and the shoe material is a thin cushioning layer, reducing friction and preventing the formation of blisters and wounds. Silicone strips are completely transparent, and therefore completely invisible from the outside. They can be used by adults and children alike. Proven quality. Great shoes and accessories for every taste and need on the official site Aliexpress.
