The iconic, proven adventure shoe offers an incredible fit, improved durability, and a grip that inspires confidence. Quick-drying and breathable mesh creates the upper on the XA Pro 3D. Sensifit and Endofit technologies wrap your foot in form-fitting security and refuse to let go until you loosen the laces. Asymmetrical lacing follows the natural contours of your foot and give your foot and ankle free range of motion. The OrthoLite insole has an EVA heel cup to help hold your foot in place when you're screaming up 2,000ft scree fields. Despite the XA Pro having a fairly low profile, ample internal volume exists in case you want to exchange the OrthoLite insole for your custom-molded inserts. The 3D Advanced Chassis minimizes lateral rolling while smoothing the transition from impact to toe-off. Dual-density EVA moves the midsole from merely soft into the realm of the mystic. This supple material cushions every footstep while remaining a bulwark against sloppy foot motion. The protective toe cap saves your tootsies so your foot looks good in strappy sandals, even after a 10-mile trail run. The Contragrip outsole is molded into toothy lugs for a reliably firm grip, regardless of how tricky the terrain. Material: Manmade, Rubber, Mesh.
