Why thicker shell walls matter

If you’ve ever wondered whether tighter, stiffer, more precise ski boots could actually make you a better skier — this episode is for you.

In this conversation, I chat with Brent Amsbury, owner of Park City Bootfit in Utah and one of the most respected boot fitters in the US. Brent and I dive into the world of what he calls “Ultra Performance Ski Boots.”

These aren’t full plug race boots, but they sit just below that level — designed for serious skiers who want more precision, better energy transfer, and a stronger connection to their skis. We talk about:

 • What defines an ultra performance ski boot

 • Why many modern ski boots have swung too far towards comfort at the expense of performance

 • How to tell if this style of boot is right for you

 • The fitting process: punching, stretching, and fine-tuning for your foot

 • Common mistakes skiers make when switching to a closer-fitting boot

 • The pros and cons — from control and sensitivity to comfort and practicality

If you’ve been feeling like your current boots are holding you back — or you’re ready to step up to a higher-performing setup — this chat will help you understand what to expect and how to get it right.
