The derby-style shoes are made of deerskin, a very fine leather known for its natural softness. The special garment-dyeing treatment accentuates the vintage style, making the shoes unique. The sole and midsole are made of buffalo leather and stitched in "blake-rapid", where a double Blake stitching joins the upper, insole, lining and midsole while the Rapid joins the midsole and sole, thus increasing the resistance and impermeability of the shoe. The bag-working process, characteristic of this piece, involves the separate application of the leather from the lining, which adapts to the shape of the shoe, giving it flexibility and softness. This technique, synonym of craftsmanship, enhances the chic and refined look of the product.
