The broadest and most popular ski boot category remains the All-Mountain Traditional group--mostly four-buckle overlap designs with non-releaseable cuffs--and there our testers find the most variety in fit profiles in narrow, medium and wide lasts and all possible flexes. These go-everywhere boots balance comfort and performance like no other category and will suit any foot, leg or instep shape and volume. While boots are getting lighter, the All-Mountain Traditional category is still dominated by polyurethane plastic, though increasingly in thin shell wall designs that reduce weight, improve wrapping for better fit and closure but maintain a strong foundation where it counts for stability and performance.
