 Poster: A snowHead

I have 7.5yr old kneebindings will they be compatible with gripwalk boots? As the boots that fit me best are gripwalk ones. Didn't really want to change the bindings quite yet!

I suspect that is a Spyderjon question. Current models are - and if lucky, older ones might be adaptable.

Well, the person's real but it's just a made up name, see?

He had a PM (as he also sold.me the bindings originally  )
However covering all basis. The instruction manual puts the choice onto the ski tech!

@SHAP, Lange LX 85HV
My previous boots were also Langes. But best part of 10yrs use had worn down the linings and the wear was quite noticeable on the souls. Snowtrax had given me some insoles previously to lift my foot a bit in them which extended there life but was noticing the movement within the boots again in December

@NickyJ, sounds good. Took the kids to Snowtrax a couple weekends ago, just to make sure they hadn't forgotten everything before out Easter trip.

@NickyJ, There's three criteria required for a GW sole to work in an alpine binding which ALL need to be met:
1. The smooth rectangular pad recessed in to the boot sole has to sitting on the toe binding AFD
2. No other part of the boot sole (ie the rubbery part) is fouling on the binding
3. The toe binding/boot interfaces pass the half mm feeler gauge/business card test. As the Kneebinding has a manual toe height adjustment you might need to raise the toe up
Pass all three tests and you're good to go - all assuming of course that your binding length/forward pressure is correctly set as well.
There's actually a good number of older 'alpine sole only' bindings that'll pass all three of the above tests but it's very binding make/model specific and it depends which make/model of boot is being used as there's some tolerance in the GW sole specification standards. But there's waaay more that fail one or more of the three tests so most of the binding manufacturers have just said "no" to the use of older bindings with GW soles to save any confusion and to remove them from any liability etc .
Failing no.2 is usually the issue, especially with rail bindings as the rubbery part of the sole often snags the rail in front of the binding. But sometimes all it takes is a quick Dremel job to either take a bit of rubber sole off or even a bit of the plastic off the binding (assuming non structural) to provide the necessary clearance etc. This is the manual you pictured puts the choice on to the ski tech - but that's assuming the tech actually knows this stuff!
Give me a call (a WhatsApp video call is best so I can see the set-up) if you have any concerns checking your boot/binding combo and I'll talk you through it.

Kneebindings made from 2017 to current have a dual GW/alpine AFD but they also offer the new AFD as a replacement part that can be retrofitted to older bindings - although it's not detailed on their website
