The COMBAT BOOT MK2 GTX , a new generation of combat boot, is designed for long marches, patrols, paratrooper jumps, mountain and combat missions. It&&';;s extremely lightweight given its intended use, but makes no compromises in terms of protection, stability and durability. Two new key features are the proven, certified ankle protection system, LOWA ASA(R) with PORON technology that absorbs shock and protects against impact to the ankles, and LOWA&&';;s new RAYFLECTA(R) leather treatment that reflects a portion of the sun&&';;s heat radiation, preventing excessive heat build-up inside the boots.
