Glazed calfskin, treated with resin which penetrates the fibre. This leather has a luxurious, glossy appearance and is also waterproof as a result of the treatment. While it is easy to clean, care should be taken to avoid scratching which could damage the grain.
Clean with Heschung renovating milk. Ideally, use a Heschung cream of the same colour as the shoe which, due to its excellent pigmenting power, will revitalise your leather. Apply sparingly, leave for a while and then buff with a wool cloth.
