I was disappointed with these spike shoes, even though they weren't very expensive. The straps did not secure the shoes very well over my shoes, even when I adjusted them properly. I pulled one of the straps tighly and the plastic nylon buckle snapped. Bottom line, when I did get them to fit and stay attached, I had to walk very carefully to avoid them falling off completely. The average person is not going to want to deal with it. The spikes are very strong and do a good job of aerating whatever you do managed to step on. If they improved the strap system and they stayed on your feet, I'd pay MORE for a product like this.
