I have fenced on the "Cheese Grater" perferated aluminum sheets for 3 years, and my shoes are hardly even showing wear, except on the back foot, the inside sole is slightly rounded.
So, fixing the footwork is the best idea! But, to answer the question about the shoes, I like the new Hi-Tec Scimitar's theory, I don't own a pair, but they look like a good idea, although I would buy the Hi-Tec Blades, which are $40 cheaper.
