It's all about space and versatility. Honestly this is one of those products that you have to read the instruction booklet to get the full value out of. But it's worth it. The multiple pitching options are awesome and the vertical internal walls are a dream.
This is proving to be a really popular boot both for staff and customers. It's robust but still light and just so versatile. Softer than your stiff full trekkers, more supportive than the minimalist light hikers. The more technical fit makes you feel nimble too.
