Natural leather shoe insoles for a new feeling in your shoe. Premium leather absorbs moisture, allows the feet to breathe, and keeps a dry climate in the shoe. A layer of activated carbon results in a climate that controls odours. The soft memory foam provides for a comfortable cushioning of your foot and reduces painful pressure. Very thin, allows for a perfect fit and can be used in all kinds of shoes. The texture on the lower side of the insole has an anti-slip function.
