Go all-in on comfort without going loose and sloppy with the Tecnica Mach BOA HV 90 Ski Boots, and see what zero foot pain can mean for your skiing. A spacious 103mm last combines with the new BOA® Fit System lower closure to produce a boot that's not only wide enough but can be incrementally adjusted for perfect pressure distribution over the top of your foot. A 90 flex is forgiving enough for most new skiers through intermediate level.
