It's a fallen arch, so I was thinking of wearing an arch support bandage under the fin. The thing is useless otherwise but maybe it will help this way. It's frustrating, because just as I'm getting to be pretty good at catching waves with the fins, my foot is bothering me--actually you get pain from the toes to the ankles with a fallen arch. Last year, I hurt my lower back and the fins aggravated that so I was arm paddling. Now that the back's better the foot's acting up. Sucks to get old and start falling apart. I did get some of those webbed paddling gloves, and I probably should just go back to arm paddling for a while to let the foot recover. The surf's gonna be tiny anyway.
