Boulder X- I like this shoe so much I’ve gotten 5 of my good friends into a pair, not to mention my mother! The stiff vibram sole and it’s glove like fit gives me security when I’m ridge scrambeling in the Darrans, boulder hopping through the Temple Valley, or hiking up to the Iron Curtain for a bit of sport climbing. The shoe’s construction allows you to toe in on small holds and grip on all kinds of rock or dirt, which means less slipping and more stability. Let’s face it, when you’ve got a big pack on, those elements are essential.
