I always get blisters on the ball of my foot if I practice for a while without any kind of protection for my foot. I am a beginner, so I know it will be this way for a while and I am also exploring ways to toughen my feet up over time. But since I am getting blisters all the time now and I don't want to stop practicing when I have them, I want to find some way to cover them. I've tried athletic tape wrapped all the way around my foot, which I think is a bit much for something the size of a quarter. It works great for at-home practicing, but I'm not a fan of how obvious it is in class. I guess I would rather use something that people don't ask about. I've also tried moleskin, which somehow always seems to come off (even with additional adhesive). I'm looking for liquid alternatives--specifically, super glue--because I definitely don't think it would come off and it would not be the slightest bit noticeable. Would this be a good idea?
