We set out to make our lightest ever women's snowboard boot, while sacrificing nothing in comfort or riding feel. The result is the Sierra W. It's a progression-friendly model with a soft flex that delivers unbeatable bang for the buck – including BOA® laces, an EVA Gravity outsole and an asym shell that perfectly matches the shape of our bindings. Inside, a heat-moldable Bronze Level liner and single density footbed will keep your feet super comfy from day one.

How to Find Your Mondo Size
- 1 Stand on a piece of paper with your heel against a wall
- 2 Mark the tip of your longest toe on the paper
- 3 Measure from the wall to the mark in centimeters
- 4 This measurement is your Mondo size
Tip: Boots should fit snug but not painful. A slight heel lift is normal initially and will improve as the liner breaks in.
