Hanging your met pads out on the clothes line to dry.
Felt is probably not the best choice of metatarsal pad for someone who wants to wear the pad directly on the foot and take a shower. Felt is water absorbent and would remain damp for a few hours after a shower. The visual image I had was of a row of felt metatarsal pads on the clothes line, each with a clothes pin. Nah, poor choice.
