Karakoram Flex-Lock

Flex-Lock: Ride Like a Soft Booter. Tour Like a Hard Booter. Imagine touring up a hard packed skin track on your splitboard: your legs are on fire as you spit and fight with every ounce of strength and focus just to keep your edges griped to the slope. You’re trying to keep your cool so your buddy on AT gear, who’s effortlessly dancing up the path, doesn’t notice your struggle. Your downhill leg is contorted and awkwardly twisted inward as you desperately try to keep your edges from rolling down hill and breaking free from the firm snow. You even resort to the karate chop technique to set your downhill foot. When you do make it to the top, you realize that you’re physically worked because of the incredible effort you just exerted. This was the story of a soft boot splitboarder until now.
