A closer look
In the waterlogged hell of World War I trenches, soldiers discovered an unseen menace: trench foot. Hours in cold, muddy boots led to numbness, swelling, and infections so severe they could cost a man his legs. Yet from the misery came unexpected progress. Commanders ordered soldiers to dry their feet twice daily, share precious grease as protective balm, and rotate socks with religious rigor. These new habits of hygiene were not just lifesaving but revolutionary, planting the seeds of modern preventive medicine. Out of awful hardship, foot care marched to the front lines of medical innovation.
