There are huge bumps on the top of my feet, from seiza. Many of my sempai have them as well, they're positively unsightly. Is it possible to do anything about these? Normally I'd just hack off the blister or callous with a pocket knife, but these bumps are really hard, like a bone more than a callous.
Hate to sound like a schoolgirl, but they really are yucky! Is there anything that can be done?
