Leather, including synthetic leather, is a material that adapts to the natural shape of the foot, preventing abrasions and blisters. After all, it's such a second skin. :) In this category you will find mainly flip-flops and sandals - even a small part made of leather really changes a lot. It also adds rivets of elegance to any shoe. Check how espadrilles, flip-flops, dolls and sandals made of this material, not only in the color of natural leather !, will look on your leg.
