I have this blister that bothers the shit out of me when im doing all the footwork for boxing drills and stuff. its on the back of my right foot and it is huge. probably 3.5cm. would you guys just continue training or what? strangely enough it has never hurt when i sprint, only when im in the gym. idk if its my boxing shoes, cos ive used them for a few months before and I never had any problems. I just started using them 2 weeks ago, so maybe my legs arent used to it, but thats unlikely. i just dont know how this shit happened. How do you guys deal with these big ass blisters?
