Pros Light and dextrous in tour mode, satisfactory ski performanceExcellent downhill performance, light weight, proven styleExcellent downhill performance, lightweight, innovativeGreat downhill performance, progressive forward flex, reliable buckles and ski/walk modeLight, high volume fit, proven buckles and closures
Cons Limited warmth, downhill performance takes getting used to, wide fit and Scarpa doesn’t recommend shell modificationsModerate insulation, hard to get in and out ofClaimed easy transitions leave you in a tour mode that is significantly compromised., binding and crampon compatibility limitedHigh friction in range of motion, smooth soleHigh volume fit, compromised downhill performance
Bottom Line Just one small step up from “Skimo Race” boots, the Alien RS is purpose built for high-speed touring and low speed skiingFor only the most specialized of needs (super wide feet, high speed climbers, big-cliff-huckers) will it be overwhelmed; this is an excellent ski boot that quietly entered the market and crushes the competitionPerhaps the most innovative AT ski boot in eight years; the downhill performance leaps ahead but some of the other innovations are “solutions without problems” that complicate real world useShares a name with the company’s resort boots, but is really a purpose-built touring boot; as such, it's better than nearly all the other purpose built touring boots we knowOn a budget and/or with wide feet and searching for lightweight touring boots for fast backcountry skiing?
