Adjusting binding for smaller boot

post #1 of 16
Thread Starter 
Okay, I'm sure many will consider this a dumb question.
I'm downsizing boots this year, going from 27 to 26. I have a sizable quiver of skis, mostly mounted with Rossi Axial2s but also a pair of Look P12s and a pair of PX15s. Will both toe and heel pieces slide to take up the room? Can I do this myself? Please tell me I don't have to have them re-drilled!
Thanks.

thats a definite ----------- depends!

on boot sole length and how picky you are wrt the midsole mark still lining up on the ski.

one size should be doable I'd think---however, I do not think the toes will be movable, just the heels

Well, not terrible picky, but...
First let me ask, will the binding set for a 27 hold a 26 safely without adjustment?

probably not.

look on the side of the boot sole, you'll see the (BSL) Boot Sole Length molded in.


raw approx boot size is 27 = 270 mm foot length 26 is 260 mm foot ength, my foot is 250mm or just about exactly 10 inches. I moved from a 25 to a 24.5 and was OK but much more and I'd have had a remount on my hands with the PX 12.

BUT i went from a 25 dalbello Krypton to rossi reverse overlap in a 24.5. LOTs of physical difference bewteen the two boots. almost like an adult to JR boot difference.

really need that BSL length to answer the Q

Many of my skis were purchased used with bindings. I have small feet so I have experience here with making bindings fit smaller boots.

With a .5 boot size change it is pretty likely that you can move the heel on the track forward enough. Full digit boot size change probably, but not always. It depends on if the heel piece is starting in the cengter of the track, sometimes they are already up or back some. The toes can't be moved without re drilling so you'll end up with a +1 feel instead of a true center or ball of foot mount. Have a shop check to be sure the forward pressure is correct cause that will change shen you start monkeying around with boot size and heel piece track location.

FWIW, I prefer +1 on everything but deep POW skis.

Okay, so the toes are fixed but I may be able slide the heels forward if they weren't set in the max forward position.
Re boots shell sizing--my understanding is that nearly all consumer boot shells are the same in whole and half sizes--that only the liners differ, ie, a Salomon xwave 27 and 27.5 are indentical except for the liner.

just list the bsl of old and new boots and someone will actually answer your question.

don't supply the info and we'll just go round and round in circles

it is not that difficult

sheesh!

Or just guess--maybe you'll be fine---maybe not.

Sorry guys but say what. Boot don't come in half sizes. So a 24 and 24.5 shell are exactly the same length. Moving from a 25 to a 24 or 24.5 is exactly the same diff. 1 full shell size or in most boots 10mm boot sole length.

Leaving the bindings set where they are and making a 1 shell size change will reduce forward pressure to the point the binding/boot system will not function.

Sorry there buddy..BUT!
When you change boots/skis you start from scratch.
Never mind so called stamped boot(shell) sizes/sole lengths.
Do enough of this and you will see practically zero forward pressure..and at the other end boots jammed into the bindings that may not release properlly.
There is simply too great a variance in track play/slop/where they are actually mounted on the skis,where the heel piece is in the track,variances in bindngs,actual stamped and measured boot sole length to guarantee the right forward pressure,the right boot sole centre...to just stuff another boot in.
It is way too easy to find ONE variance off,setting/adjustment right at either end of the scale without ANY tolerance for change.
First thing you have to do is physically put the old boot in the binding on the bench and eyeball where the heel track adjustment is and where the forward pressure indicator is. This will give you an idea how much you can move the heelpiece. If it is an obvious no go..=drill. If it is a maybe/iffy..try the boot. If it is a go=adjust the boot,adjust the forward pressure. Yes,yes of course there are times when you eyeball it and it looks good/doable and you stuff the new boot in,no adjustment. Some heel pieces have a very high tolerance for different boot sole lengths and the forward pressure still remaining in the acceptable range even without adjustment. Some do not.

In a word..if you have a sizable quiver..there is an excellent chance that some are mounted at either end of the range. Don't just assume that they were all measured and jig drilled the same.
Prepare for some drilling.

we've heard from the boot guys, binding guys and wiseguys all said the same thing in wildly different word counts.

Is this true if the boot brand, model, or year made is different? I have a pair of Langes and Rossis that I think are the same size, but the Langes are WAY older. The sole legnths are considerably different cause the Rossi toe lies out over the binding toe more.
post #12 of 16
Yes it is true if I understand your question. Within models a 24 and a 24.5 are the same size shell. Also applies to 29 and 29.5 and everything in between. Between years of course there may be changes, but within the year it applies.

It really doesn't matter. I was only disagreeing with the point about shell design and differences between shells. In the end Arnold is correct. Put your shell in the binding, view the forward pressure and adjust correctly. End of story.

If you have several skis, adjustment method may vary. Some may require heel adjustment, some may require moving toe and some may require complete remount. Impossible to know without putting boot in binding.

Okay, so I've got my new boots. The boot sole is just 7mm shorter than the old boot and the binding heel pieces all are set at the back end of their adjustable range. I have enough range to slide the binding forward and hold the boot heel.
Now what about din? Does it need to be adjusted for the shorter boot?

Thanks.

Bindings DIN is calculated using a chart, there are ranges for boot sole length... since you have been careful NOT to tell us any pertinent info in this thread, we can't really answer that.

telling me your boot is '7mm shorter than my old boot', then asking if it needs to be adjusted is like, well it's like this:

I just bought a new vehicle, it gets 5mpg better gas mileage than my old vehicle... does it get good gas mileage?

Well, that really depends now, doesn't it?

You mentioned Xwave 27, you didn't SAY that was your old boot, but if it was, it would have a 315mm sole length, new boot 7mm shorter = 308mm, that would be a readjust.

...but if it was, say a 323mm bsl > 316mm then no readjust.

It really depends.

Thanks for that link, Ghost. Question answered.

For those who's feathers I ruffled--didn't mean to do it, I really am a tech jong. For the record, I went from 315 bsl to 307, 8mm difference. Thanks for all your replies.
