Body glide helps my thighs from getting chapped but never helped my feet. Two years ago I had a blister the size of a small sausage that ran under all 5 of my toes on one foot with 4 days to go on the vacation. Not fun.
Last year, each morning I sprayed all of our feet with spray deodorant and we wore "moisture wicking" socks. They were awesome! I'd be sweating all over but my feet were dry! No blisters for anyone that trip!
