Tactical Research TR360 KHYBER Hot Weather Lightweight Mountain Hybrid Boot was specifically designed for all-terrain use. From rocky mountainous terrain to hard pounding concrete roads, the Khyber II will outperform when tested in any environment. It features an upper constructed of 100% suede cowhide leather and breathable nylon Cordura. It features a long wearing VIBRAM “IBEX” outsole for excellent traction on rugged terrain. A low profile sole reduces weight and A highly cushioned, shock absorbent midsole attenuates shock during intense physical activity. A patented TR-1 insole provides firm footbed support to reduce fatigue during long sessions of wear. With excellent design features to add to comfort and durability, such as its lace-to-toe lacing system for a customized fit, the TR360 is a top choice for multipurpose use. This boot has been replaced by the TR350 Khyber II Hybrid Boot, which is the AR-670 compliant model.
