When putting in the miles on the trail, having a lightweight performance running shoe makes all the difference. The Salomon S/Lab Ultra 3 Trail Running Shoe is a supple, lightweight trail running shoe with a new Matryx mesh upper for extra breathability and lower weight. The Contagrip rubber outsole supplies grip and traction in nearly all trail conditions, and the Quicklace closure system is super easy to use and provides a secure closure. The midsole provides a supportive platform with moderate cushioning, and the knit cuff ensures a secure hold and comfortable fit.

Fast, fun and secure

I've used it several times
Size Bought:

I have put in a few runs in these including a 20 miler and i love how secure and sleek the upper is. Yes, it’s hard to get on, but once you do it just feels fast and agile on the trail. It’s a lower stack height and a bit firmer than others i.e Hoka but feels responsive. I’m stoked to use it in an upcoming 50k. Def a Salomon fit which is a bit narrower than others.

No grip at all on wet surfaces

I love those shoes, one of my favorites for fit and comfort on long distance training runs and ultra trail races. However the rubber has absolutely no grip if the terrain is technical and wet or muddy. How come such expensive shoes have no grip? You have other models with good rubber, why not use the same for a long distance shoe? I just don’t get it. I run on the mountains most of the time here in Seattle and this lack of grip is a huge disappointment. I wish I could wear these shoes more often, but that’s never going to be the case. I have been wearing Salomon all my life and buying the s/lab was such a big investment and now I have an excellent pair of shoes I can only wear for about 3 months of the year…. Huge disappointment.

Fits like a GLOVE!

Was hesitant at first, but after a day or so of breaking them in, these things are incredible! Can’t wait for many adventures up in the mountains with them.

Great Trail Running Shoe

This is a great shoe for trail running - light and form-fitting enough that your foot doesn't role around in them. Only complaint is that the lugs wear down relatively quickly (maybe 6mo - especially if you include some road in your runs). I'm a loyal customer of these shoes after having gone through many pairs.

Like a glove!

Definitely very form fitting. I usually have difficulty finding shoes for my narrow feet, but these fit the bill. Feel very stable and comfortable. Can't wait to get them into the mountains this summer.

I love hiking and trail running with my dog. I am a personal trainer and fitness is number 1 part of my life. I time myself during my some of my hikes and trail running days. I noticed my new salmon shoes has been helping my performance and I have been finishing my trail running faster by 5 to 10 minutes compared to before.
