SPIN ULTRA 2

I tested the spine ultra 2 on a testing by scarpa in France. Great shoes very stable and firm. All my shoes are in 42 including these scarpa (Hoka, Saucony, Salomon). I juste have the kjerag 2.0 on 41.5 because i want a narrow fit.

These fit a half size bigger than the previous Spin Ultra version. I agree the foam is nice. I'm very curious to see how folks feel durability is... I wore ~25 pairs of the Spin Ultra v1 (sole trail shoe since 2019) with nary a durability issue. I had to warranty my first pair of these after 30 miles as the upper was detaching from the sole on BOTH shoes. The warranty pair I got sent has the various overlay pieces coming unglued after ~40 miles. That seems cosmetic to me so going to keep using them but it's a pretty poor start. I'm hoping the best for these... the foam is nice and they fit my foot well.

That's because those are not even running shoes, but for hiking. The Rapid LT is an approach-shoe. I mean coming from Salomon, everything is an upgrade, I guess, but that is a weird comparison. That being said, Scarpa arguably makes some of the best mountaineering boots in the world, but all of their trailrunners absolutely suck, except maybe the Spin Ultra 2, which was halfway decent.

There's absolutely no running shoe that really works on wet, slippery rocks, you'd need crampons for that or whatever. I just did a 32k/2500m mountain crossing recently in heavy rain, and it was absolutely abysmal, although I'm an avid runner and mountaineer. It took me over an hour more than usual and I really reached my limit several times during that run. For everything else there are special rubber compounds that are more sticky than regular running shoes (like Vibram Megagrip). A lot of performative trail running shoes (Scarpa Spin Ultra 2, Hoka Tecton X, Hoka Mafate X, Dynafit Ultra Pro 2) use this very sole, others use a similar system (La Sportiva Prodigio Pro). They perform very well in a dry alpine environment, but have, as I said before, their limits in rain and mud. Also the additional grip adds to the already high abrasion, which means your soles will disintegrate even faster than regular runners. Not as bad as the early Salomon Speedcrosses, but don't expect to do 1000k in these boots. Edit: spelling

La Sportiva Prodigio Pro or Scarpa Spin Ultra 2. Depends on if you have a Scarpa foot or a La Sportiva foot. I’ve used both and the La Sportiva worked better for my feet.

I just commented the same. The Spin Ultras have been incredible for me in 2025

Scarpa. Got a pair of Scarpa Spin Ultras last year...they're def in my top 3 fav shoes of all time for mountain running. Check all the boxes with 0 complaints....think they were on sale for like 70 bucks at the time cuz no one in the US buys em. Wish I bought like 5 pairs...can't find em anymore
