- Durable Construction: With heavy-duty YKK medial zipper, a bellows tongue to keep debris out, and protective rubber heel and toe cap, these boots are designed to withstand the rigors of the great outdoors.

- Eco-Friendly Elements: The boots feature 100% recycled laces and webbing, 100% recycled fleece lining, and a 5% recycled PU removable footbed, aligning with your commitment to sustainability.

- Odor Prevention: The boots are NXT treated to prevent odor, ensuring freshness even after long hikes.

- FloatPro™ Foam Midsole: The FloatPro™ Foam midsole offers lightweight comfort that lasts, ensuring that every step is a comfortable one.

- Enhanced Traction: With the Vibram® IceTrek outsole and Vibram® traction lug for improved grip on uneven terrain, you can confidently navigate various surfaces, even in cold, icy, or snowy conditions.

How to measure?

1) Place a piece of paper on a hard floor with one end to the wall. Stand on the piece of paper with the heel slightly touching the wall.

2) Mark the end of your longest toe with a pencil for both feet. Tip: It's easier if you let someone help you with this.

3) Measure your marking from the wall (heel) to the longest toe for both feet. Take the larger of the two foot length values and compare it with the sizing chart.
