The SCARPA Alien Boots employ some radical technology to obtain a race weight at a reasonable price. With walkability similar to hiking boots and skiability similar to heavier kit, the Aliens are quickly becoming a go-to boot for skimo racers and light and fast tourers.
SCARPA designed these with a more comfortable last than other lightweight boots, and used a BOA closure system instead of a buckle in the forefoot. This allows you to get a precise fit over your instep without consulting a boot doctor with a heat gun. The laced upper buckle system is integrated into the walk/ski mode switch so you can transition between uphill and downhill modes in one simple step. Once pointed downhill, the Alien Propulsion Tech frame provides a sturdy platform for driving skis harder than you would think for a 2 pound boot.
