Unconventional shinbang

This is mainly aimed at Tom and Onenerdy, but for anyone who can answer, go for it.

Anyway, I have some Nordica Double Six's (equivalent of the 2 star) which is 115 progressive flex, and I am severely overflexing them (5'11" 145lbs). This is causing a problem since they have the flex block tech in them which stops flexion after a certain point, but I am flexing them past that point and creating the shell to bow out. The 45 degree buckle stops me from flexing them any further though, and I am getting shinbang from landing switch mainly and crushing my boot up until the boot folds over the 45 degree buckle and then my boot stops and its like a wall. this obviously gives some pretty bad shinbang. I am planning on getting some new boots at the end of the season if I can afford it, but I need a way to stiffen my current boots up for the upcoming season. I talked to my local bootfitter and he said that he doesn't believe in booster straps solving this problem for me. He suggested welding the cuff to the bottom piece of the shell (depending on if the shell is the correct style to do that in the first place).

First, I don't know if it is the right shell, and I don't know how I should go about welding them together. Second, does anyone else have any suggestions?

I love these boots and will probably just get the Schiller pro or 1 star for an upgrade, but If there is a way for me to dramatically stiffen the double six's up, I would be more than happy.

Shinbang is highly related to a boot being too soft for you. If you are severely over flexing a ski boot, it means your shin is essentially gliding up and down the tongue coupled with your shin bowing over the cuff (especially on switch landings if you lean a bit uphill).

Without seeing you/in the boot, I would say this is 90% your problem. Unfortunately, if you are bellowing out the boot as you say then normal tricks to stiffen up the boot will be uneffective. It's time for a stiffer shell/cuff, but one that yields the proper amount of flex for you (read: not so stiff that it causes shinbang from not flexing).

OK so if its my problem there's a way I can adjust to fix it correct? I already tighten the boots as much as I can while still being comfortable and the boots really do fit amazingly

That's what I was getting at in my first post: if you are truly over-flexing the boot and the lower shell is drastically bellowing out, then there is no way to stiffen the boot up. You could try a foam injection liner, which would stiffen it up but it would also drastically (perhaps for the better, but it's not certain) change the fit.

Your best bet would be upgrading to a stiffer model in their range.

Yea I understood what you were saying in the first post but I just can't afford anything right now and was hoping for anything that might help or that I could change so the problem would lessen. Well thank you I will see what my bootfitter thinks of injecting the liner

A foam injection liner will still run somewhere about $300-400 so it's not a cheap option. Honestly probably don't spend any more on these boots. Save up and get somthing which meets your flex needs.

Bumping this thread after I went to try on some boots, and I found that the Technica Mach1 130 seemed to fit very well, and I even had space to go down a full size (a first for me). The bootfitter said it was the hot item for Technica this year, but he also said he was skeptical about it working for park (seeing as there is no shock absorbing features along with it being alot stiffer).

I am also skeptical to get them because they are a 4 buckle boot, and with my protruding bone on the top of my foot, the 3rd buckle down is directly across it, so no amount of punching will fix that pressure point, but he said that Technica's shell was designed to prevent pressure on that area as well as a few others.

I have been told that the 3rd buckle will not be a problem for me in other boots by other bootfitters, but it has always been a problem, and caused me to distrust the 4 buckle system. Should I trust these Technica's or stick with 3 piece designs that I know don't give me this pressure point problem?

If he truly believes that it will not be a problem...then ask him if he will guarantee it. If he will, then you have no risk going into the 4 buckle system, and you can just take them back if it doesn't work out.

Buckles don't cause instep pressure, a last shape that has a low instep causes pressure. For example, if you had a 3-buckle tongue design with a super low instep, and a higher volume 4-buckle design, the higher volume 4-buckle design will not cause as many problems as the 3-buckle. Not because of its buckle count, but because of its instep height.

If the Mach1 is too low volume in this area, you should be looking into the new Hawx 2.0 130. This is the boot that Gus just won the Dew Tour with and definitely one of the best options for finding the best fit: fully heat moldable shell, cuff, liner and adjustable flex and adjustable forward lean. If the Mach1 is a bit too low volume for you, this should definitely be a boot you should look into.

ok The fit was incredibly impressive, and definitely in the top 3 fits I have ever had right out of the box, possibly the best, but I had no instep pressure on Drop kicks, while I did however have instep pressure Nordica Firearrow's.

my foot is very low volume, but my instep juts out a ridiculous amount, so its been tricky for multiplbe bootfitters to address this problem. Again, My Nordica's had to be punched to fix my instep pressure, and they definitely have a higher volume than the Technica's while still fitting the rest of my foot.

I also forgot to mention in previous posts that the instep only sees problems in the park like when I land backseat and flex my tails or ski in the powder with camber skis that require me to pull up on my tips. This is what is scaring me about 4 buckle boots because no matter what you do, the location for tightening the boot is still over the instep, so there will alwasy be metal there (from conventional 4 buckle designs) having force against your lift.

I am also no longer available to Atomic and Salomon boots after the shop carrying those brands recently shut down.
