The Boulder Summit combines the minimalist features of the Boulder Boot with the outsole of the Outlander. This means these boots offer substantial grip without weighing you down, flexibility as you navigate uneven terrain, and the wide toe box means ample space for your toes to spread out fully. The rubber outsole incorporates 4mm deep lugs and zig-zag grooves for superb traction in even the most slippery situations.

Available in Rugged Bark - a full-grain, oiled leather, which can be reconditioned overtime to retain its best waterproofing - and Nitro - a fully waterproof Nylon and vegan-friendly option.
