First of all the size was all wrong. I wear size 10-1/5 walking shoes but could barely squeeze my feet into a size 12. Then they scraped my ankles raw, my baby toe is still numb, and my calf is still tight from all the heel lift (even after I pumped up the air thing as much as it would go). I had to buy an insert that helped a little but then it made my arches sore. Any more questions?
