I ordered a pair of shoes and then went to read reviews. I cancelled the order within 3 hours of ordering. Received computer generated reply but shoes were still shipped 2 days later. Once received, I tried walking in them for about 2 hours. I felt hobbled. My feet hurt and shoes were so stiff you really couldn't walk properly. I returned them and asked that I not be charged for shipping either way as I had cancelled the order in plenty of time. I finally received my refund one month after they received my shoes back (UPS tracking) and I was charged for shipping. Never order Gravity Defyer shoes.
