Trench foot
The mainstay of treatment, like the treatment of gangrene, is surgical debridement, and often includes amputation. Self-treatment consists of changing socks two or three times a day and usage of plenty of talcum powder. Wherever possible, shoes and socks should be taken off, feet bathed for five minutes, patted dry, talcum powder applied and feet elevated to let air get to them.
Trench boot
The 1917 Trench Boot was an adaptation of the boots American manufacturers were selling to the French and Belgian armies at the beginning of World War I. In American service, it replaced the Russet Marching Shoe. The boot was made of tanned cowhide with a half middle sole covered by a full sole, studded with five rows of hobnails. Iron plates were fixed to the heel. It was a great improvement, however it lacked waterproofing, leading to trench foot.
