Winter trail running shoes with built in spikes. These fit like a 7.5. I didn't size up enough, so I've only worn these a handful of times before I decided they were just too small. They're incredibly light and waterproof, just not the right size. Barely used so they're seriously like new. MSRP is $355. Bio-based Dyneema® upper is lined with a G+® Graphene membrane for increased thermoregulation. The sole plate has carbide spikes that cannot be removed. For use in icy and snowy conditions.
