First off, the upper is not only more breathable but more durable and secure, it features a static webbing cinch starp at the midfoot, a sandpaper textured toe cap, and improved drainage holes. The outsole got a complete makeover with decouples TrailClaw and multim-directional, craved lugs for increased traction and reduced weight. And just in case all the new features didn't already have you stoked, the StoneGuard is completely new and now resembles the skeletal structure of a foot for dynamic flexibility and better performance.
