If success in the medium width category means appealing to a broad spectrum of skiers and different foot shapes, then the Spyne 110 can hang a “Mission Accomplished” banner without fear of being mocked.

Testers thought this step-down, 110 flex skied just fine, holding its own against a bunch of boots with brawnier numbers. It’s adequate for all but redline expert skiers or larger guys who simply need the support of the medium-width big brother Spyne 130. The softer flex and slightly lower-than-average cuff height of the Spyne 110 make it a great choice for guys with shorter legs and big calves who need their boot top to hit just below the widest part of the muscle.

Other than the cuff, testers rated the fit decidedly "medium," with score averages that center punched the category range. The revamped liner has a more supple construction and the re-shaped toebox is a success, providing good out-of-box fit for testers across the board. The multi-layer, multi-density Intuition foam liner can be heat molded to improved effect on a hot stacks but few test forms indicated a mandatory call for it. That's a big step forward for the Spyne 110.
