Hi folks, anyone else have issues with pain in the ball of their foot with all the jumping exercises? I think it started when I was traveling and was working out without proper shoes (and on a hard surface) but I've switched to wearing athletic shoes for any jumping exercises, and it still flares up pretty bad sometimes - just in one foot. It's been a few months since I first noticed it. If it gets back, I switch to low impact for a while and then switch back, but it seems to come back. Any ideas?
