Last summer I stupidly let my feet get sweaty in a pair of (good quality) walking shoes in France. As a result I had the most appalling case of athlete's foot which involved splits in the skin and was quite disabling. I tried all sorts of creams from the GP, none of which worked. Wasn't keen on the pills you can take as they are known to cause liver damage . The "foot lady" we have recommended a couple of things and they are much better now but I'm desperate to avoid a repeat. I have two pairs of Skechers which are made of synthetic material and my feet are wide (size 42). I walk a lot as it's my main form of exercise. Please provide recommendations for walking shoes which keep feet healthy.
