A breakthrough in alpine boot design, this next-gen concept was developed in conjunction with alpinist David Göttler who sought a super-lightweight high altitude training/acclimatization boot. The flexible LOWA REPTEX abrasion-resistant upper is injected with PU “scales” that mimic a reptile’s protective skin, thus replacing a traditional heavy rubber rand, while the VIBRAM® Alp Trac® SL sole features Litebase technology that substantially reduces the weight and thickness of the sole without affecting its traction or wear resistance. Combination crampon compatible. 100% vegan. Featuring a durably waterproof/breathable GORE-TEX lining to protect feet from the elements.

"This is an amazing boot. It's as light as a shoe, low profile and comfortable as a mid-height hiker but supportive like an ice boot! Super comfortable and yet, technically oriented, these boots are so sweet! Simply put.... I love these boots." – LOWA Ambassador Jeff Shapiro
