On one foot I have two toes that rub together when I play and have formed kind of a lingering tender bump on each toe at point of contact. It's not a blister, if anything they feel kind of callousy but a little raw too. I've tried a few different medical tapes and bandaid wraps to try to prevent the sore spots from getting worse. Currently I'm going with paper tape directly on the skin. I had previously put a bandaid on first then wrapped with tape but it seemed to allow for abrasive movement. It's not causing me any problems or pain when playing but I just don't want it to keep getting worse and worse. What's the best way to deal with this?
