People experiencing homelessness face constant exposure to cold, moisture, and prolonged walking, making foot health a serious and often overlooked issue. Socks quickly become wet from snow, slush, or sweat and are difficult to dry, leading to skin breakdown, blisters, and infections. In winter, wet socks accelerate heat loss, increasing the risk of frostbite. Once feet are painful or infected, people often move less to avoid discomfort, which further reduces heat generation and worsens cold injury. This creates a vicious cycle where infection and frostbite reinforce one another, limiting mobility and making it harder to access shelters, food, or medical care.
