Trench Foot was an infection caused by standing in the wet for a long time and not being able to dry your shoes and socks out. Your feet would go numb at first and then turn red or blue, and if you got gangrene you may have to have your foot amputated. Brigadier-General Frank Percy Crozier argued that: “The fight against the condition known as trench-feet had been incessant and an uphill game." The only way to get rid of trench foot was to dry your feet and change your socks several times a day.
