They are 100% handmade using naturally tanned leather, cotton thread, and a pure rubber outsole. Leather detailing covers the elastic for a sleek look. They are comfortable for all day wear, can be dressed up, and are stylish. Note that the sole is made of natural leather and rubber, which can feel stiff when brand new. The leather softens with wear and conforms to your foot. Because leather is a natural material, there may be slight color and texture variations.
