Crispi Thor II GTX

rated 5.0 of 5 stars
photo: Crispi Thor II GTX backpacking boot

A stiff, but relatively lightweight boot. Suitable for very rough terrain, off trail and with heavy loads.


  • lightweight (for a stiffer boot)
  • grippy outsole
  • roomy toebox, but not overly wide elsewhere


  • it's a boot, so considerably heavier than a trail runner (but necessarily so)

I have several hundred very tough miles on these boots, mostly big game hunting, but also a few multi-day snowshoe trips. These are NOT the shoes I'm going to grab for general backpacking; I wear trail runners almost exclusively for that. But for very rough terrain, generally off trail and normally with heavier loads (sometimes north of 100 lbs when successful big game hunting), these are the shoes (boots) I grab.

Crispi is an Italian boot company who have concentrated on the US market and especially big game hunters. They have a dozen plus models of boots ranging from sturdy trail runners to very heavy insulated mountain boots. The Thor II is the model I own and at the lighter end of their range of boots. But it's at the stiffer end of their range of boots. I've found this to be important when in rough country and carrying heavier weight.

I previously owned a pair La Sportiva boots that filled this role, but sadly discontinued. I tried a couple of more La Sportiva boots, but could not get the fit I wanted. I want a roomy toebox, but I want the midfoot and heel to fit more precisely. For some reason, not easy to find. The Thors fit (my feet) perfectly. Very little break in needed. They fit well right out of the box. I do have wide feet, they are offered wide sizes as well.

They have a Goretex liner which in shoulder season and winter is a plus (not so in warmer months in my experience). They use a Vibram outsole that is nice and sticky on rocks and grips mud and snow pretty well too. With the amount of use they've seen, I've been very impressed with the wear.

The boot (boots in general really) aren't going to appeal to a lot of folks hiking and backpacking; trail runners almost always suffice and are much lighter. But if your adventures take you off trail in rough country and especially if the loads required for that adventure are higher, this boot is worth taking a look at—as is their entire line.

When something works well for me, I stick with it. I recently purchased another pair of Thors as the original pair won't last forever and I want to insure I've got a boot I can rely on in the future.

Thor II's



Several hundred very rough miles with these boots; including several trips where loads ended up being in excess of a 100 lbs.

Nice synthetic boot 🥾—withstands the harsh Northern Nevada rocky trails.


  • Lightweight for the protection it provides
  • Warm enough to wear in zero-degree winter temperatures
  • Looks great 👍 and easily worn for everyday casual wear.


  • Possibly more colors. But can’t seem to find any.
  • Not sure what others are quacking about regarding waterproofness? Goretex breathes and contrary to popular beliefs it will eventually absorb water 💦. Most likely the wetness others experience is sweat 😅.

I own another Crispi boot 🥾 used mostly for shooting and outdoor activities. These kicks are lighter and you can get away wearing them in a semi-formal office setting.

I use the Thors for mountain biking. They are plenty tough and lightweight. The sole is firm and you won’t feel sharp jagged rocks anywhere through the sole to your feet.  


Mostly used for mountain biking. Short hikes with dog 🐕 go. Nice lightweight boots!
