The toe plate of the blades on the Jackson SoftSkate is riveted instead of screwed in, so the blades cannot be shifted to compensate for glitches in a skater's stance. I have a student in them who has not been able to hold onto a RFO edge because of this. I noticed that the last adjustment to my new boots/blades was a leather shim under the heel of one boot, so I tried this with my student's skate. The heel plates are screwed in, and I was able to unscrew enough to slide a thin shim into place. I did not remove any screws, but just lifted the heel plate a little with the end of a screwdriver. There were no problems tightening up. Voila! RFO edges are now a piece of cake for her. I've been afraid to recommend this skate, which was my favorite for beginners, since I've had two students with this kind of problem.
