I wore fencing socks during the hammer dash and, OMG, they did a good job. Would require more investigation, but they are padded on the front, which stops the wind/keep a bit warm, while the back eliminated is made to stay dry. The biggest advantage is the foot padding, where the shoes for road usually provides no insulation. about as expensive as cycling socks. where a bit hard to fit in during the transition, but it might be nice, combined with leg warmers or just instead of… definitively going to try again!
