I think the videos are great.
But for me, if I don't tie a double knot at the top, they slip over time, so I do.
BTW, if you can't tie a bow tie without loosing tension, as your finger in the middle of the knot comes free, recognize that a bow tie is a double slipped granny knot. In other words, tie the initial overhand (where one lace is looped around the other), then grab the laces closer to the hooks, so you are holding a loop (technically, a "bight") in each hand, and complete the second overhand with those loops. That way you never need to release tension.
I know it's a little slower, but I also initially tie the bottom loop loose, and lace things up moderately tight all the way up the holes. Then I go back, and tighten each level loop in turn.
Perhaps it's because I don't use waxed laces, but I find that if I let go of the laces at each level, the way he does, they slip back a little, and won't be as tight. So instead of just letting go, the way he does, I put two fingers over the holes, so they can't slip, and tighten with the other fingers. That's part of why I need two iterations - my hands can't stretch enough to tighten while using the two fingers, so I only do the two finger thing the second iteration. When tying the hooks, I don't let go, but keep tension on the laces while switching hands.
It seems like we all spend a lot of time figuring out how to lace our boots so they work. Such a simple skill, yet we have to relearn it for snug lacing! Sometimes skating makes us feel like little kids again
I used to use a lace hook, but with this method, I don't need it. Like the video guy, I have no callouses or blisters. Maybe someone who used hand lotion to make her skin soft would need gloves, or would get callouses or blisters.
Not many people even can do this, but laces can be too tight. You don't want laces so tight they create a break down crease by direct pressure, nor do you want the "lace bite" to make your feet hurt or go numb. And, like the video guy says, you still need to be able to flex and point your ankle forward and back.
The hockey kid in a local shop claims it's a lot easier with waxed laces. He says the laces don't slip, so you can tie everything normally. I've never tried waxed laces. I wonder if there is a downside. The ones he had in the shop only fit hockey boots - too wide for my holes.
One last thing. Some people here have said that lacing is a lot easier if you use the "Lace Vice" device, where you just pull the laces, then slide them into the sailing-style jam cleats.
