  1. I don't think profiles on their own are driving lateral crossovers, they are just one of the pieces of the puzzle that are driving advances in skating. By trying different profiles, hollows, steels, sharpenings, holders etc skaters are able to select the most beneficial combination to suit their style of skating. Think of it as incremental changes, 1% here, 1% somewhere else, add them all together and now you are talking significant change. fwiw the last I read was that McDavid uses a 10' radius and Barzal was on a triple when he won the fastest skater comp.
  2. Paradigm or evolution? If you told any coach 10 years ago that one of the fastest ways to skate up the rink was lateral cross overs you would have been laughed off the rink. Even with his near perfect bio mechanics, could McDavid use his lateral cross overs as effectively in boots from 20 years ago? And traditional power skating techniques, aka Laura Stamm, long considered a gold standard are now been rethought with different techniques and approaches been developed. All of this because of changes in boot technology, design and analytics. Ever since boots have been made, manufacturers have been trying to make them stiffer with the belief that reduced ankle articulation would lead to better and faster skating. Reduced ankle articulation would shift the control of the skate to the biggest and strongest muscles in the legs - glutes, quads etc - and this would enable more stability and control. Lace up as tight as you can was part of this paradigm (originally they had to because the boot really offered no other support). Then over the last 10 years or so new materials in boot design created ultra stiff boots but the lacing message remained the same, generally coming from established people in the sport like players and coaches who have been around for years - that's what I was taught so that is what I will teach. My belief is that the data and research coming out now and over the next few years will alter boot design away from the quasi ultra stiff ski boot, for a technique and health perspective. The boot will evolve into a design that has different flex zones incorporated into it. From under the ankles upwards you will be able to get different, custom flex zones, the boot will still wrap around the foot but the ankle will be able to articulate within a form fitting boot. We have never had this mix of design before (stiff lower / flexible upper), graf was starting down this path with its flex zone but the rest of the boot technology was behind what other manufacturers were producing. How such a design might change or create a new paradigm for skating we can only speculate at this point but I would suggest that the changes in boot design over the last 10 years or so has led to different approaches in skating techniques and that we will continue to see this in the future as technology in boots continues to evolve and skaters learn to take advantage of this.
  3. Lots of research referenced to back this up (warning - it does delve deeply into things), note the dates of the research as they are all recent. All the new research I'm finding is pointing towards dropping eyelets and looser laces to support ankle articulation. If your knees ever wanted a reason as to why you might want to change from those fully laced, extra cranked around the ankle lacing patterns that most of the "dated" advice out there tells you to do, this is it. https://adamvirgile.com/2019/08/08/the-impact-of-ankle-motion-on-ice-hockey-performance/
  4. Haha, it is, the tongue can flop forward and this really screws with your cross overs. For game time you lace up like this (bottom 3 to 5 eyelets), tight or loose depends on how good you are skating like this and your preference. Daryl can just pull the boot off as he ties very loose.
  5. I have but the performance hit for me is too great at this stage, I'm slowly closing the gap (versus laced up) but it's a long term learning process. I train with no laces and currently play with the bottom 4 eyelets laced up only (I move between 3 to 5 eyelets laced up depending on the boot I'm in). As to playing in games, this guy (Daryl Evans) played a chunk of his NHL career with just the bottom 5 eyelets done up and there are pics of him playing in all star games with no laces.
  6. Eek, that's a tough question because I have different preferences. For retail skates I like the one piece construction because I find it has much more lateral support at the sole level. For me this is one of the key areas if you skate lace free. The Jetspeeds are nice but too soft when unlaced (but this was 2 years ago and my mechanics have changed a lot and I need to give them another go). The AS1 and AS3 are fine but my current skate is a custom extra stiff apx2 I picked up off eBay. If you want something close to the one100 when laced up then I'd go with a Jetspeed, the AS1 / 3 are in a completely different realm when it comes to stiffness.
  7. I still have my One100's (last skated in them in Jan) - my Jetspeeds would be on par, my AS1's and AS3's are much much stiffer (all are retail skates).
  8. I got them when they first came out and have 3 of them, different colours and weights (4, 6 and 8). I agree with you, they are rubbish unless they are on a completely smooth ice like surface. A green biscuit kills them.
  9. If you or the shop are worried about the stress a shim may place on the boot then you need to plane the shims so the boot geometry remains the same. Take the back point of the shim (let's say it's 2mm high at the back of the boot) then you draw a line that follows the shape of the boot to the toe where it sits on the chassis. Now you plane the front and back shims to follow that line. This is much more work but it ensures the boot shape does not change, just the pitch.
  10. I have no experience with TF7's but have shimmed roller, ice and figure skates for pitch. I have never come across a skate that failed in the sole because a shim was added to the rear or front. Whilst the pitch of the boot may change, there is not a lot of flex thru the middle section because the front and rear are fixed. 2mm was what I would have started with if you wanted a noticeable change however be prepared to try 2 or 3 different heights until you find the one you want.
  11. And here is what the doc also said - "1 in a 100 million chance" (along with a dozen other comments about risk, mitigation, freak accidents etc). Those are the odds you are asking manufacturers to spend money on, get real. Here's a guaranteed 100% chance of avoiding this accident - DON'T PLAY, go find something else to stand on a soap box and harp on about. Or here's your answer, I've found something protective that covers the whole head and most of the body, as you said yourself, shins are just bones so who cares about those.
  12. I don't disagree with you, I think that manufacturers could do a lot better but it's a complex issue. Imagine if you have something covering the area but it disintegrates or deforms from a puck strike sending shards into the ear? And whatever you put there it needs to not impair the hearing or look dumb or cover anymore of a players face. Imho they will address wearing of cages or hybrids first (because someone will die from a slapshot to the face) before they do anything about the ear area.
  13. Sad answer is no. My understanding is it caught him under the ear, the biggest issue is the damage to the carotid artery. Even with a cage there is no protection there other than a piece of plastic if you still have the ear guard in place. It's a freak accident (and from a simple dump in) but one I'm not surprised hasn't happened before (a puck to the facial area) given the propensity of pros to lie down in front of a player who is taking a shot. If you worry about this then I'd suggest you also need to wear neck guards, wrist guards, groin guards and a host of other guards covering areas where a puck or skate blade may strike. And whatever you do, don't look at motor vehicle stats or else you would never leave home to drive to the rink. With any sport, there are degrees of risk, you need to weigh them and decide if you are happy to participate. fwiw I've seen guys nearly die from playing soccer, who'd have thought that kicking a ball around could kill you?
  14. I will ask but I suspect not, a certain large worldwide company (I can't say anymore than that) has paid / paying the University for the rights to the work and I am bound by a pile of nda's. Pissed me off no end especially as I was one of the founders of the research but such is the commercialization by the Uni of research work. I now honestly don't know if anything will ever be published about the pronation, lace free skating, skate mechanics, skate design analysis and a host of other spin offs we studied. I now understand why there is very little research about skating openly published, a lot of it is purchased and then taken in house.
  15. I went back to the University research group I have been involved with and asked the question why linear crossovers may be faster. This is only a theory because I for sure as heck am not good enough to test it (and we don't have the tools) but the modelling they did consistently gave the same result, you can skate faster up the rink using linear crossovers but it's very specific. They analysed dozens of clips of McDavid and others in action. One thing that was consistent is the arc they take when doing the crossovers for speed is very similar and flat. By skating in a flat arc, the skater is able to use the G forces generated from the arc to increase the power they are generating into the skate blade. Like a racing car, the faster you go the more downforce you get. Too much arc and the edge will slip (also see next point), to little arc and you can't generate enough G force. And from analysing the crossover stride they are using, they concluded that it's as close to the mechanics of the way a human runs than any other stride in ice skates. So by mimicking how a human runs they are able to generate maximum power into the crossovers but if the arc is too tight or too flat then the crossover is compromised away from the running motion. AGAIN - this was all modelling and theory but the maths held up and analysing how McDavid skates when at full speed doing the crossovers supported the theory.
