The Trango Ice Cube GTX gives you everything you want in a lightweight climbing boot, without any extra frills. Their stiff midsole keeps your calves from getting pumped, while a flexible ankle cuff lets you pull out all the latest tricks on technical mixed climbs. A built-in gaiter keeps snowy socks at bay, all in a package that weighs less than a pound per boot. The traditional lacing system lets you dial in the fit, whether you're slogging up a long approach or honing in on small rock edges. These boots are fully waterproof, and despite their lightweight design, they'll keep your feet warm on all but the coldest days. Available at Uphill Pursuits; $550.
Update: Our test pair of the Trango Ice Cube GTX has held up through three seasons of winter climbing in Montana, along with trips to the Cascades, Alps, and Patagonian Andes.
