"Several reasons. Many of the survivors ended up barefoot after fleeing in a hurry. In the disaster zone, feet get wet and then extra cold at night, especially in currently freezing weather. People often forget about socks in favor of more obvious items like blankets and jackets. Receiving a new, fresh pair of socks provides a moment of comfort. If those socks arrive with a caring note as well, it’s very heartening for survivors. If you’ve ever been stuck in a pair of wet, cold socks or no socks at all, perhaps you remember how soothing it felt to pull on a warm, dry pair. Survivors have already requested socks on TV news.
Socks aren’t primary support, but a token of care that will last beyond their small mid-crisis comfort. All supplies exist here in Japan, so we wanted something that delivered meaning past the need of the moment, something more special than what people get from emergency teams and government supplies. Military socks are not the most comfortable. Small joys matter. A March 17 CNN articleobserved about the survivors: “It was the little things that helped them retain their sanity as an end to crisis still seemed distant.” The next day, an AP story said a city hall worker reported his town needing “gas, vegetables, socks, underwear, wet wipes and anti-bacterial lotion.” Most importantly, shelters themselves are requesting socks."
