PETROSOLAUM
Stone Derby Garment Dye Cowhide Black
The PETROSOLAUM Stone Derby refines the classic Derby through considered leather processing and streamlined construction. Zeolite tanning develops the leather without conventional tanning chemicals, giving the material a distinctive character while reflecting a more environmentally considered approach. Mackey stitching joins the upper, insole, and outsole in a single seam, creating a flexible construction with a clean, close profile.
