Periodicaly I get blistering of the sole of my foot between my 1st and 2nd metatarsal heads. Just happened again when I went for a treadmill run after swimming last night. Anyone have any suggestions, sock, anything that might help? I was once told by a foot guy that I have a poor metatarsal arch and he recommended somekind of inexpensive support in my shoes, which I haven’t purchased. Is this why I blister?
