New without tags. Vibram Men's KSO FiveFinger athletic shoes in grey / black camo pattern. Size 11 US / Vibram 45.“The KSO is arguably our most successful FiveFinger to date, mainly due to its versatility. We added this back into the mix a few years back to celebrate the rebirth of a legend. When you're scrambling up a rocky bluff or bounding along a riverbank, the last thing you want is gravel and grit seeping into your FiveFingers. So why not Keep Stuff Out! The KSO has a snug fit, one of our most minimal sole constructions for maximum ground feel, and a breathable, quick drying upper. The KSO also features a thin, abrasion resistant stretch polyamide and breathable stretch mesh that wraps your entire foot to do just that. A single hook-and-loop closure helps secure the fit. Non-Marking XS Trek performance rubber soles are razor-siped for sure grip.”Size 11.5 (or 45 on Vibram site - see size chart photo)I’m also listing this as a size 11 according to the size chartFast shipping from smoke free and pet free home.Stock photos added for reference
