What problems did trench foot cause?

Trench foot, caused by prolonged exposure to cold, wet conditions, led to severe pain, swelling, and tissue damage in soldiers' feet during World War I. If untreated, it could result in gangrene and amputation. Additionally, it significantly impaired soldiers' mobility and combat effectiveness, contributing to psychological distress and lowering morale. The condition highlighted the dire need for improved soldier welfare and better equipment in harsh environments.
