“Towards [sic] the end of WWI, the armies developed techniques for preventing Trench Foot,” blogger Perry Walters says on the Kansas World War One Centennial Committee website. “First, they provided an elevated wooden floor in the bottom of the trenches. They enhanced the trench drainage systems, and they also developed a buddy system where each soldier was responsible for his buddy’s feet being dry and clean.”

Armies also instituted regular foot inspections.
