Perfect for individualists: The Think! KAPSL lace-up. Sustainably made from particularly soft, supple and chrome-free tanned nappa leather and fitted with a chrome-free tanned leather lining. It makes for a great wearing experience. The flexible rubber sole gives the shoe stability and is fixed to the upper by a robust seam. The interchangeable insoles can be easily replaced with orthopaedic or custom insoles as needed.
