Epiphany for a blister free foot

So, yesterday during my 5 mile training run, I had an epiphany!! Last time I hiked the Canyon, I had blisters as big as quarters on my toes - nasty, hurtful, fun-hating blisters. What if these next few weeks of training, I switch shoes every day or so. Each shoe rubs and wears differently, making my feet tougher more durable and potentially blister free. Hmmmm, I'm going to give it a shot. Anything is better than quarter sized blisters!!!
