Flat Shoes For Summer

I was chatting with one of my friends tonight, and while I was extolling the virtues of the Airwalk slip-ons and canvas flats I found at Payless today, she mentioned that she needed to look for flat open-toed shoes for summer. They had to be quite flat (no or very low heel) because she has severe back and knee problems and doesn't want shoes that will aggravate either, somewhat dressy, and have some sort of ankle strap so that her foot will stay put in the shoe. That definitely leaves flip-flops and thong-style shoes out of the equation! (Oh, and whatever I chose should theoretically be available at a store in Van for the purposes of accessibility. :P) Because I had some extra time on my hands, I wanted to help her do a little cyber-scoping. Here's what I came up with.
