Howdy---I too have flat feet, they were supposed to keep me out of the military, but I still served in both the Navy and the Army for 12 years, and I ran marathons for 10 years, and on my feet for 25 years working as a cook. When it comes to shoes for what ever purpose I don't pinch pennies, I get the best that I can afford. I have trouble with shoes that have high arches, I just shop around until I find the ones that feel right. That is about all you can do when you have our problem. I now wear a running sandle as they are much cooler than shoes here in the desert, I have some heavier sandles for hiking. About the only time my feet get to hurting any more is pushing the cart for my wife on her weekend shopping marathons. Taku John
