Charge just as hard as you would in a pair of alpine boots.

Reap the benefits of your long slug up the mountain with the Garmont Men’s Radium Thermo AT Boot. The Thermo gives you the same stiffness and responsiveness as an alpine boot so feel free to open it up and launch off of cliffs on your way down.

  • A unique overlap design allows the lower shell and cuff to operate independently for more freedom and comfort when you walk, yet it buckles down securely to descend like an alpine boot
  • Pebax lower shell and cuff makes for a lightweight, responsive, and least temperature sensitive boot
  • The a.d.d. wrap ski mountaineering shell gives you a custom boot-fitter fit which provides room for the ‘6th toe,’ first metatarsal, navicular bone, and heel spurs
  • Cuff buckles are moveable to custom-fit different size lower legs
  • Hook-and-loop power strap helps secure your foot in the boot, and combat the dreaded shinbag
  • Rabid sole grips rock when you scramble up a wind-scoured peak

Solid Performing AT Boot

Skiing on a budget has me out every day in my Radiums. These boots are warm and comfortable for lapping at the resort, riding the sled to the skin track or ripping untouched pow. The walk-mode is fluid and these boots clamp down tightly. Obviously, these are not intended to be a daily-driver, but they are a little softer than I would like. Besides that, sick boot!

Radiums Radiate (w/ intuition liner)

I have used these boots on tours up to Muir on Rainier, Snolquamie BC, and Baker BC (all WA state). So far they have performed excellently. The did not have any problem driving a 116 rockered ON3P BG ski. I have used them with both marked duke and barons. I have the new touring Intuition liner in the boot and it has to be the most comfortable boot I have ever worn.

Me: skiing steep lines and dropping up to 10 feet. 170 lbs. 6'2

Pros: I really like the latch system on the upper two buckles. Having the buckles in the same catch all day is nice and reduces transition time. All the pre-punching they do to the boot makes them super comfortable for people with messed up feet like me. The rubber sole has been working well. For my weight they have no problem driving a powder ski.

Cons: The latch system on the upper two buckles can freeze up. I had to hit the button with the top end of my ski pole a few times to get it working again. So far no problems getting it free but could be a problem. Also note, these have more volume then Dynafit boots with the same width. They maybe too sloppy for low volume feet.

Is the Radium boot compatible with Marker...

Is the Radium boot compatible with Marker Jester bindings?

Responded on

No, they probably will not, but has anyone toyed with jamming them into Salmon pilot style bindings?
I'm wondering if some sanding would make them fit into an adjustable toe-height type binding.
