Since getting introduced to wheelies and manuals, I've struggled a lot with balance, and I think I may have happened upon a significant improvement: changing up my lacing. Apparently, there's a remarkable number of ways to lace your skates up! And while some people take full advantage of this as an opportunity to flex their style, it can also be a way to really lock in your skate fit.
In the picture below, I've changed my lacing from an out-in(from outside the eyelet to inside on the cross between eyelet pairs) on the left skate, to an in-out (from inside to outside the eyelet between eyelet pairs) on the right skate (obviously I'll lace them both like the one on the right😉). I hope that makes sense, lacing really is kind of complicated. Regardless though, the fit is night and day. On my manuals, I feel my heel lift off and my toe shift forward in the toe box in my left skate, while the right heel only comes up a little bit, and the toe stays LOCKED in place, and I feel a lot more in control. Best of all, I haven't felt any discomfort from pressure, if only a little numbness.
It says it's for ice skates, but I think there's some good bits of advice for roller skate lacing as well. Cheers!
