We recently moved to Phoenix where people pretty much wear flip flops year round. For some reason it is wreaking havoc on the heels of my feet. I pumice, moisturize, etc on a daily basis and it's not helping that much. At the end of every day it looks like I haven't done my heels in months. Does anyone know of a good product to protect your feet from the elements? Thanks. I love this forum BTW. There's so many interesting threads.
