I use PowerGrip straps, which cross over my foot diagonally.
So far I seem to have no issues with whatever shoes I wear. I tend to wear comfy Merrill mesh-top running shoes in the summer, and insulated warm heavy hiking boots in the winter. I have to adjust the straps larger for when I switch to the hiking boots.
Now you guys have me wondering about maybe buying stiff shoes....even though I'm comfortable enough in my running shoes.
