Beast Carbon Ski Boot

At three pounds per boot, the Dynafit Men's Beast Carbon Ski Boot is light on your feet so you can reach the summit before sunrise. Unlike most superlight ski touring boots, the Beast feels more like a powder-charging freeride boot on the ride down. This beast boasts Dynamic's SnowDynamic Concept, which uses a streamlined design to help you shred the deeps and steeps without losing any speed. 

A full Pebax and carbon construction keeps the Beast light and stiff for advanced backcountry skiers. The boot's Precision Lock System includes a secure ski/walk mode that allows for a massive range of movement in walk mode for easy skinning. The insulated Custom Ready liner includes thermo-moldable Ultralon foam for a fit specific to your foot's contours. Dynafit gave the grippy sole large lugs for bootpacking up rocky, slippery surfaces.

Wear all day boot

  • Familiarity: I've used it several times

This is a great touring boot. I've added an insole to accommodate my mangled feet. When using the walk mode I loosen the power strap and top two buckles all the way and adjust the one on top of the foot closest to the ankle out one notch. This seems to provide plenty of movement without creating hot spots or blisters. The black bars that go over the top two buckles make getting back into downhill mode quick and easy. Have used them for resort days too and they are plenty stiff. Toes stay warm and dry all day. Construction is what you'd expect from Dynafit at this price point. Will last many seasons. I did not have the boot heat molded or punched out anywhere because they fit so good right out of the box.

Good stiff shell lousy liner

  • Familiarity: I've used it several times

This is a proper stiff boot that tours very well for its free ride category. The claimed 45 degrees rotation might be overselling it a bit. The interlocking shell system really transfers the power from my foot to the ski well and makes the flex progressive. It pushes my 193 Prior Overlords just as good if not better than my old Scarpa Freedoms they replaced, plus they tour significantly better and weighs 15 oz less in the same size. The liner on the other hand is junk, maybe I have been spoiled by Scarpa's stock Intuition liners, but the Dynafit Custom Ready minimalist liner didn't even fill out the shell. I couldn't get the boot comfortably tight on the tightest settings. I could not tell the difference between pre and post heat mold. It didn't take long for me to buy some Intuition Pro-Tour Liners Medium Volume which made them actually fit a human foot. The power strap is also far too small and doesn't do much but get in the way when taking it on or off. Intuitions are not cheap and the after market purchase increased the price of an already expensive boot which is why I gave it 3 stars. If it was packaged with a proper fitting liner and a decent power strap it would be a 5 star boot.

My Favorite Boot

  • Familiarity: I've used it several times

This is my fourth pair of boots, and I love them. They are super stiff and feel like an alpine boot. I haven’t noticed any downsides while hiking either. I have considered replacing the liners with some aftermarket ones but am worried that the boot wouldn’t be as stiff anymore.

My Favorite Boot

Stiff, but not snugg

    I have been using Dynafit boots for years. Always loved the fit and ability to charge downhill. My last pair was a set of Vulcans.

    These boots are stiff. The closest to a real alpine boot i have found. I would LOVE these boots except one problem: the liners.

    The liners are about 1/2 the thickness of my vulcans. Amd after heat molding they filled out nicely at the foot, BUT i cannot get a tight fit at the upper two shin buckles. I have moved the buckles to the tightest hole, and on the tightest buckle setting there is still play in the tongue.

    The result is the boot feels a bit sloppy, and you have to be real agressive to maintain pressure forward.

    So far this is a dissapointment. And I am hoping it can be resolved in someway.
