Beast Ski Boot

You never thought you'd see the day when you could enjoy both freeride and touring performance in one boot, but with the Dynafit Women's Beast Ski Boot, that day has arrived. Built for long days in the backcountry when turns are the ultimate goal, this boot is both lightweight and stiff, letting you save energy on the climb and giving you the ability to power through turns on the downhill.

The Beast is engineered with Dynafit's Snowdynamic concept, which means it's built to ski deep powder with minimal loss of speed. The Precision Lock buckles sit close to the inside of the boot, reducing drag and preventing them from getting side swiped by a rock or stump. This setup also prevents the build-up of snow and stops it from entering to the rear of the cuff. A custom light liner can be heat molded for a seamless fit and enhanced performance. This precise fit adds to the warmth of the boot. An anatomic 102mm last gives your foot some wiggle room, which is nice for the climb, while the cuff provides a range of motion ideal for touring.

  • A freeride boot built for big tours in the backcountry
  • Stiff flex allows you to power through turns
  • 102mm last fits a wide range of feet
  • 45-degree cuff rotation with release for walking
  • Precision Lock System guarantees precise power transmission
  • Thermo-moldable liner provides a customized fit
  • Master Step heel insert is wider to work with Beast binding

Worst ski boot I've ever owned

  • Familiarity: I've used it several times

I've had these boots for a few years now, invested over $1K in them to try and punch them out/custom footbeds/liners....several times. The lightweight isn't worth it with these boots. Even after the shortest of tours, I have skin peeled off my heels and toes, every time without fail


  • Familiarity: I returned this product before using it

Tried these on in the store, figured I share with the BC community. The foot bed was very comfortable and the toebox shape was great for a narrow foot with a little bit of shape. The acute pinch on my shin when flexing the boot was terrible, I can’t imagine trying to ski hard pack in these, ouch. If you have longer legs/lower legs: beware the plastic shell is on the short side, I felt like I lost so much leverage, and was being cut off at the shin. The Backcountry picture doesn’t show a power strap, the pair I tried on in the store had a pitifully thin power strap that looked like an afterthought. There wasn’t enough room on the shell or liner for it, so when I cranked it down it awkwardly went half on the liner and half on my leg...

Great upgrade from the Mercury

  • Familiarity: I've used it several times

I've only taken these boots out for a couple test runs, but so far I'm really impressed! I just upgraded from the Dynafit Mercury (RIP) and here are a couple of the differences, both good and bad:

wider last (102) and consistent BSL length with other brands 23.5 (the Mercury was a 268, and my toes could feel the difference of 10 mm). Overall, the boot was much more comfortable out of the box.
Stiffer tongue allows for a more "alpine boot feeling" while skiing.

The lack of removable tongue does make these boots stiffer when ascending, but honestly, I'd rather have the better descent.
Heavier than the Mercury
The power strap is terrible, I'll be replacing the power strap immediately.


  • Familiarity: I returned this product before using it

I tried these on full of optimism...but when you flex forward the shin pinch is immediate. Saleswoman agreed she felt the same thing and tried to show me how to dampen the pinch with foam/padding. The tongue has to be vastly improved. The foot itself fit fabulously, would have been great.

P.S. Hey Backcountry-ers....how about listing the weight of these puppies? Seems kinda important for an AT boot!
