Cover miles on backpacking expeditions with the long lasting durability and comfortable support that the Mammut Women's T Aenergy GTX Boot brings to your foot. Its Gore Tex Performance Comfort lining gives this boot exquisite waterproofing that leaves the boot with wonderful breathability to keep your foot as comfortable on the tenth mile as it was on the first. The Hybrid Shell blends a sturdy 2Tone PA fabric with softshell to make the boot hard only where necessary, leaving the rest with soft support for enhanced comfort. It also combines two different yarns to create a technically functional boot that's also visually attractive. Mammut added a Liquid Rubber Protection over the synthetic overlays to boost durability. This boot's Base Fit lacing system provides sliding webbing that transfers the lace's tightness down to the soles for an improved grip, increased safety, and enhanced comfort. The honeycomb structured 3D Textile inner material absorbs moisture fast to quickly dry your foot when you work up a sweat hiking under the sun, and Memo Foam covers your instep, shin, and ankle with long lasting cushioning thanks to its excellent elasticity. Mammut added an EVA wedge midsole with good damping properties that absorb shock and vibrations to keep your foot comfortable for miles. This boot's rubber toe cap prevents any painful toe stubbing against stumps and protruding sticks. Its Vibram Scale sole consists of multi directional mid height lugs in a scaled arrangement that ensures maximum grip over all kinds of terrain, and its Rolling Concept provides a natural foot roll to prevent fatigue and to help reduce the danger of twisting your ankle in the middle of nowhere.
