At SPINGLE, we use leather which is not usually used in sneakers, and a variety of processes using a wide variety of leather to challenge ourselves to create shoes with a wide range of appearances and expressive character which is born through the various textures of each leather and during processing. SPINGLE shoes are made in a high temperature kiln using the vulcanization process which involves high heat and carbonization, so we only use quality products which have passed strict checks on factors such as shrinkage and discoloration etc. Our commitment to these materials, which bring out the unique “character” of unevenness and wrinkles unlike any other pair as they are worn, and hand work, allows the creation of a one-in-the world pair of shoes with unique character. In the future we will continue to challenge ourselves to all possibilities in order to deliver to our customers shoes they have never seen before Excellent very Gently Used Condition. No flaws noted
