My boot fitter turned my shells into mush!

post #1 of 24
Thread Starter 
Let me try this again. My new Technica Diablo Magnesiums were radically softened by my boot fitter's effort to give me more room in the instep (navicular bone). Can somebody suggest how this happened and is there anything I can do to get the original stiffness back?

Thanks.

if he heated and blew out toe "6th toe area" then there is no reason for it to have caused a flex issue

The Mag is a soft/very soft boot for many skiers (ok, for most skiers). The 100? flex index doesn't mean anything. The reason this boot (and this goes for the other Diablos,too) is soo soft is that the plastic is very soft, especially in the instep area. They probably wanted to make it easier to put on/take off than the Icons.

I do not know what your bootfitter did (perhaps you could give more details), but if you have a high instep, dropping the bootboard could solve this problem.

The Diablo Mag's forefoot is soo wide that it takes a really wide foot to make room in this area

Jamie -- Thanks for your response. The flex was significantly stiffer before he blew out the shell. See my earlier post "bootfitting experience."

I noticed there is another thread on the same subject.

The answer is pretty simple: you are flexing the diablos too much. They were way too soft for you from the beginning (a 200lbs. guy in the Mag?). Seriously, you need a stiffer boot. You will probably break the diablos. For your weight, i would recommend the 130 flex, but it is only available in the Race, which is lower volume and narrower. In this case, i would look at another brand. Nordica offers some good boots like the Beast or Speedmachine if you want a wider forefoot.

At this point, I'm more concerned with why the boots flex more AFTER the bath and the punch-out. Any ideas?

I can tell you that tecnica uses three different types of plastic for the diablos. I did not like this design from the moment i saw it, so i'm not surprised it does not respond well to grinding or softening or... anything.

There are a couple of bootfitters who post here and they will probably help you.

FWIW, i weigh 155lbs. and i tried the Fire (90 flex?) and they were rediculosly soft. Again, IMO the problem is that they are too soft for you (even w/o any softening done).

I'm 45 years old, and after 30 years of shin bang (with scars to show for it), I thought I'd give myself a break, but this is ridiculous. Thanks for your help.

If you want to stiffen flex, you could put two bolts in (Dobie design). This is what you can do if you want to stiffen flex, but i do not know the design of the Diablo in the area above the Achilles. If you do this, you will be connecting the lower with the cuff. This will also make the boot more responsive (but it is another story). If i remember correctly, there was a thread on tgr on this subject. I will look for it. Hopefully, will find it.

maybe its a form problem not a hardware problem

i am 240 and skiing dalbellos"kryptons" and have no issue with boot..also was on a icon and wasnt a problem"they were 70 or 80"

Did you know that the krypton has the best flex pattern on the market?

That's not it. I can ski. Actually, you're missing the whole point of my post, skidbump. I only want to know why the boot flexes more after the fitting work, and I'm hoping that some knowledgeable people might have an opinion.

Flatlander,

Just trying to eliminate the variables, so forgive me if these are obvious. Are you comparing the flex in the shop before, with the flex in the shop after modifications? If you're comparing the flex when you used it, i.e., on the hill, the cold would have stiffened the boot. Also does this boot have a flex adjustment that was changed to facilitate working on the boot?

SnoWonder -- Good thought, but I'm comparing my actual experience skiing the boots from one day to the next after the boots were worked on overnight. The next day was considerable colder, so I've ruled that out.

I tried the diablo Mag and it was wayy too soft for me at 215lbs.
It wasn't the cuff. It was the lower boot that was bulging out at the sides.

The only way I could get it to stiffen was to overtighten the instep buckles. But I would never ski with that much instep pressure, ever.

So, by loosening the instep, they decreased the stiffeness of the lower boot, allowing the lower boot to deform and flex more easily.

Buy a different boot at your weight. You will be much happier.

"Navicular" is vastly different than "sixth toe".

One would have to see the punch to make a guess, but there is no good reason why a navicular punch should make the boot all that much softer....I mean the boot is like jelly to begin with...

An aggressive grind in that area would make some difference, but not likely a startling one.

I think you nailed it, Gapic, and it's what I've suspected. I'm a patroller, and I've been looking for reasonable performance with all day comfort (I mentioned my shin bang troubles earlier). Before the boot work, the Magnesiums performed OK. I don't blame the shop, really, but I think Tecnica should put out some kind of warning that messing with the shape of that soft plastic might make the boot rental fleet-worthy.

At this point I think I'll give them to my jibbing 14 year old, and take his Head S-12s (a better boot and $45 on eBay).

Weird. I've done both navicular and ankle punches on those boots and never gotten any similar complaints.

However, both before and after you can bend those things with your hand. Its got to be the softest boot six hundred bucks can buy...

I hate to state the obvious (since you're a patroller), but shin bang is not due to stiff forward flexing boots. It's due to a poor fit where the boot is not "following" your leg closely when skiing. There's lots of threads here about how to solve shin bang problems; moving to a really soft forward flexing boot isn't one of those good solutions.

I've been banged up by some notorious rock boots in the past (a pair of Caber Azzurros comes to mind). After years of skiing in a succession of race boots, some better fitted than others, I'm now looking for smoother, somewhat easier forward flex. I've recently lost the PCL in one knee, and I have to go easy on my tib/fib rotation. I believed the kinder, gentler high performance hype from Tecnica and my shop.

A little obvious... but did you check that the flex setting on the back of the boot is in "lock"? I think you can further increase the stiffness, by putting all 4 screws in the cuff setting plate.

Thanks, twinc, but they're at their maximum. I'm almost certain now that the problem is the soft forefoot (made softer from punching) deforming with pressure.
