A comfortable, lightweight alternative to similar mountaineering boots that weigh a couple of pounds more, the award-winning La Sportiva Trango S EVO GTX features a waterproof and breathable GORE-TEX lining to protect your feet from rain and snowmelt without stifling the interior vapor transfer. One of the best features is a ground-breaking 3D Flex ankle hinge that allows side flexibility without compromising the front-pointing stability. Compared to other traditional climbing boot designs, the La Sportiva Trango S EVO GTX is almost luxurious in comfort and support, which means you"ll probably end up using it for backpacking and just about any other backcountry activity you can think of this season.
