I have a problem with my right skate. My foot flops on the inside edge constantly, which makes it difficult to do crossovers on one side. I have had a lift put on the inside heel to get my foot to the outside but it doesn't help. Also, it the skate tends to get really loose after skating for a half hour and my ankle shifts. I tie my skate really tight, use a skate key, and actually gotten blisters on that hand from tieing it so tight. What else can I try?
