FIRE RESISTANT LEATHER UPPER
Chemically treated to be fire resistant, our rough-out leather is known for its natural durability.
VIBRAM® S587 FIRE & ICE OUTSOLE
Ideal for rugged and high-angle terrain with an oil-and slip-resistant compound that still maintains traction in extreme cold and hot environments.
To accommodate more people, we've made this boot in extended sizes. We recommend women select 1.5 to 2 full sizes down for correct fit.
WTF PLATFORM CONSTRUCTION
For optimal rigidity and stability underfoot, we combine a full-length polypropylene board with an integrated steel shank in this construction method.
HOW IT FITS
The 851 last is an update to our popular 850 last. This last fits true to size with an athletic and supportive fit while providing ample room in the toe. Offering a specific heel shape that locks the heel in place for better fit and comfort on the back end of the boot, this supportive fit is ideal for those needing high mileage performance from their gear.
