nah these dont hold up during the rigors of kendo. prevention is better than trying to heal a hole in your foot. i have taped my left foot and both big toes since the second week of my kendo training. sometimes the tape comes off (not good during jegeiko) but mostly it keeps the skin on my foot where it belongs. last night at training i felt what i thought was tape comming off my right foot during jegeiko. not tape but lots of skin. im not sure how i did it but obviously my technique needs some attention. and i need to tape up both of my feet before training. after only a year training i am still a beginner so i know i have much to learn. expecially things like walking properly when skin is missing from my foot.
