Heel Lift in Ski Boots

post #1 of 11
Thread Starter 

Hello All, 

 

I recently decided to acquire a stiffer boot for this season, from 110 flex to 130.  At a recent ski swap I picked up a new pair of Tecnica Inferno R130 boots, these are the 2011/12 model, in bright orange.  I believe these are a plug, 95mm last, they had never been skiied, but I could see they had previously been worked on in the sixth toe area and in the Ankle.  I typically need work done in the same areas, and the boot seemed to fit pretty well, so I pulled the trigger.  However, I do have one concern, I noticed that I get some heel lift when flexing/walking in these boots.  I have custom footbeds, so I'm wondering what else could be done to secure my heel a bit better, or whether I should ditch the boots and move on.  These have the thin lace up liner, so I'm also wondering if getting a slightly thicker liner would help.  I'm planning on seeing a bootfitter, but am open to any suggestions.

 

And yes, the boots are sized correctly, I don't think I could go any smaller without crushing my toes. 

 

Thanks

do you get heel lift when skiing? 

 

can you give us a shell fit measurement please?   in mm?

Hi Mn
After verifying the size, I would check yor range of ankle motion. If there is less than 12 degrees of ankle flex in your ankle joint, heel motion is the result. If your range of ankle flex is adequate, then Look for a heel wrap. If. It expertly installed, the wrap can shift your foot forward and compromise toe space. It is also worthy to critically analyze your footbed for ideal accommodation and interfacing with this new boot.
A ZipFit Gara liner would likely lock your foot.

I wear a size 9C street shoe, actual measurements are 267mm length.  Boot is a size 25.5 mondo, last is 95mm, but there has been a bit of grinding in the ankle and toe (similar areas where I've had work done on previous boots).  In the shell, I have approx 12-16mm behind the heel.

Hi MNSking10,

 

It sounds like the shell size is correct from your info---just a couple of suggestions and one question.

 

Tighten the ankle buckle (second from top) until it hurts (couldn't stand it tighter) then back it off until it is just comfortable and see if your heel lifts.  don't tighten the other buckles but install the power strap around just the liner inside the front shell pieces and snug it up securely.

 

Question:  what is the circumference of your calf muscles at the top of the liner?  A large calf muscle will push the knee forward and use up some or all of the available ankle range of motion available.  That boot also had a lot of forward lean (compared to newer models) as I recollect.

Hi Mike, 

 

I don't know the circumference off the top of my head, but I've got skinny chicken legs, so I would imagine this wouldn't be as much of an issue.

does you heel lift, when you point your toe and try to lift your heel?

does you heel lift, when you keep the whole boot flat on the ground, and just flex your ankle forward ?

It lifts a little in both cases.  I also notice that when I walk with the boots on, you get the characteristic squeak since the liner is lifting slightly in the heel with each step.

so is the liner moving in the shell, or the foot moving in the liner?

 

 

have you skied in this to see that it does happen on snow?  and not just in the living room?

The boot you have is I believe a 95mm last and you are in a size smaller than your foot measures.  Heel lift is unusual I'd say in this setup unless you have dorsiflexion issues as BootDr mentioned.  However, there is a tendency for skiers to absolutely crush the boot when testing for lift in the store when actual range of motion required to ski is substantially less.

I've only tested in my living room at this point.  The liner feels like its moving a bit, and the foot in the liner a bit more.  My ankle (and therefore heel) doesn't feel locked in

 

I have an appointment for a boot fitting @ Hi-Tempo next Saturday.
