I walk about 6-7 miles each morning. I wear good quality distance walking shoes. About a week ago, I got new shoes, and subsequently experienced pain, burning and itching on the outer aspect and heel of both feet. This comes and goes, in both feet at the same time, and lasts from a few minutes to half an hour. I have tried Desenex, Benadryl cream, and lanacaine, with only temporary relief. I have alternated pairs of shoes, given the feet a day off from walking, but nothing is helping so far.
