I love my Salewa’s Pro Gaiter Mountaineering Boot. Of all the mountaineering and double-walled boots I’ve tried, this by far exceeds and earns my 5 stars. I like the walk/climb feature where you can turn the amount of tension on your sole to adjust to your activity. I also found that on less demanding activities such as hiking with snowshoes, the built in gaiter has basically eliminated the need to carry additional gaiters that go on over my boots and pants. The boot is also very warm but breathable at the same time. Although they are slightly heavier than other boots, it’s worth the added weight!
