Our new soft ground sole gives superior grip on wet terrains. It is quick draining, for minimal wet weight, with a lightweight ankle collar for support.

Built around the concept, less is more. Less shoe, less weight – more freedom to move. We had a vision for the lightest movement shoe possible; a shoe that followed the natural shape of the foot and had the least possible interference with human movement.


Excellent Product

The SG trail shoe is fabulous! It’s got a tight sock like fit, I I have to wear mine with sock liners and nothing thicker. But it is a rocking shoe! It wears well on the trail and around town. I love the green color I got - totally goes with my look. Fabulous Product! Buy it!


This was the perfect combo of traction for trails and minimal shoe. I have been barefoot for over 10 years and I am extremely picky regarding my footwear when I’m training. I would highly recommend this shoe to any fitness or nature enthusiast.

It’s a love hate relationship!

My first impression of this shoe was amazing! I pulled them out of the box and was so thrilled. Then I noticed that the shoe doesn’t have a tongue or any laces.. so it was a slip on. I was a little discouraged because that wasn’t what I was expecting but I decided to try that out anyway. But I’m not sure if these are made for people with very small ankles or if mine are larger? But that part began to really squeeze on me while I was at work trying them out, and I could not get the shoe on with any socks I owned so I was nearly late because I spent so long in the parking lot trying to get the shoe on. Throughout the day I noticed my walking form was better than in my normal shoes but I just couldn’t shake the fact that I wasn’t wearing socks and that my new shoes were rubbing my Achilles’ tendon all wrong. But all in all I like the shoe, I just need to try them for a little bit to see if that part loosens up? Luckily they have a 100 day guarantee so I can try these out and decide whether I need to re order. I would definitely recommend this shoe, but with a tongue and laces! That’s my only hold up.
