A Very Deep Dive on Bootfitting, Pt 2: Your Questions Answered by Master Bootfitters, Sam and Kara (Ep.214), BLISTER
Sam Tischendorf dialing things in with a customer

In the second installment of our “Very Deep Dive on Bootfitting” series, Blister reviewer (and bootfitter) Kara Williard is joined again by Master Bootiftter, Sam Tischendorf. But this time it is all about you, the audience, as we make our way through a bunch of your questions. Sam and Kara explain some of the technical mysteries — and at times, controversies — within bootfitting, such as forward lean and ramp angle; provide a deeper explanation of why custom insoles are so imperative as the foundation to a boot’s fit; the differences between rigid and flexible feet; they make a case for women-specific ski boots; and they end on some horror stories and Sam’s true feelings about DIY bootfitting.

  1. ”It looks pretty schmick!!”

    Awesome episode. Bit like listening to a conversation that makes you just pitch in and ask questions (yeah I am that guy. And will usually buy beers in the end). As a designer, love calling out the truths about ”female” boot moulds and male-driven design decisions.

    Something that kind of was touched but wasn’t discussed with, and what I personally struggle with is this: The holistic biomechanics – skier size + weight versus boot fit & materials in fitting, especially at the opposite end of spectrum (me: 6,6”, 100kg, fairly aggressive, directional skier). This is where I feel the limits of some bootfitters’ knowledge might come to play as well. I’ll shoot a more detailed question regarding this over the form.

  2. It’s been years since I purchased my last ski boots. How much does the average 120 flex boot stock liner pack out after a few days? I found a model that fit my foot my foot shape perfectly at my local shop and my fitter and I were going back and forth between the MV & LV models. With the MV, I felt like I could leave them on for an hour without unbuckling. The LV made me a bit numb in the forefoot after 15 minutes. Do you think the MV will get sloppy after a few days, or will any packing out be counteracted by tightening down the buckles?

    • Short answer: assessing a fit over the internet is near impossible but I would bet a large sum of money that the MV is too high volume (too sloppy) for your foot. The tightest the boot will ever be is right now, in the store – it will only get looser from there. So, that your foot gets slightly numb in the LV is not a bad thing. Get a proper footbed, have the liner heat molded and you’ll most likely be good to go. Liners will also pack out faster in a shell that is too high volume for you – your foot will simply move around more and thus pack out the liner more quickly. Ultimately, extra room can always be made but you can’t really shrink a boot down.

  3. Can’t wait to get way more nerdy with this series. Really hoping for more detail and the “why” not just the “what” in future episodes!
