|: What's up with the double toe stoppers? One on each end of the skate, 2 per foot, 4 to replace them all at one time!???
The one at the rear is for braking while going downhill. It's more effective than dragging a foot behind you, unless you're into skating downhill backwards. (I do that occassionally for something different. Make sure the intersection at the bottom is clear before you start out though.) :)
