Use Viscol

Viscol makes the leather soft and pliable and also waterproof. Viscolized leather remains soft and pliable under continuous hard service, even when it is worn in salt water or in snow. Viscol is a solution of a rubber-like material which amalgamates with the leather substance and is not driven out of the leather by heat or by water, the way oils are. Its beneficial effect is lasting. Leather that is treated with Viscol wears several times as long as leather that has not been thus treated.

Viscol is sold by many of the Post Exchanges and by most shoe dealers. If you can not procure it at the nearest Post Exchange or from your shoe dealer, write to
