Sizing Advice:

Ready to check out our newest boot? After much refinement, we find that the Boulder Summit may just have the best fit yet! So how does it compare to your other beloved Lems? If you have the Primal 2 and find that they fit just right, then we suggest you stick with that same size. If you find that the Primal 2 is a little too roomy for your comfort, order a half size down. If you are a Boulder Boot fan, we find that the Boulder Summit fits a little longer than the Casual Soles styles. If you have any questions, feel free to contact our customer service at info@footworksrunning.co.uk.

*Original NATURAL SHAPE: Widest toe splay with a fully wide fit.



If you’ve been holding your breath for us to release a Boulder Boot style that can properly tackle the trails, you can go ahead and release that breath. Now take another, and another, because you’ll be huffing and puffing up and over mountains and along stretches of dirt and rock in your spiffy Boulder Summit boots. Rain? Mud? Snow? Sleet? No matter, these boots are highly water resistant and will keep those feet as dry as possible despite what Mother Nature throws your way.

The Boulder Summit combines the minimalist features of the Boulder Boot with the outsole of the Outlander. This means these shoes 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.
