I bought this show thinking it would make me faster. It did not. Now I owe my neighbor $200 because I bet him I could beat him in a foot race. I think hes taking performance enhancing drugs because he has a real short temper and threw my trash can down the street when I told him I didn't have his money yet. I thought these shoes would give me the edge I needed. They are comfortable though. Maybe I can give them to my neighbor as a peace offering.
