I've owned some for years but don't use them at all anymore. I just hated not being able to move my feet around at will. Plus, they always ended up hurting my knees, even though I had lots of float, and my feet got sore from being in the same spot. They do not make one faster. But lots of people like them so it must just be me, I guess. They were designed for racing and hardcore offroading where they definetly help in keeping one's feet on the pedals. You should try them though. You won't know if you will like them until you do.
