Testers said the Viron 12 Vacuum CF skied much like a tuned-down Ranger Pro 13—and that's still saying something. It has a more upright stance than the Ranger, and it's substantially wider—both of which made for a more comfortable, performance ride. They said it was quicker and more tuned-into the snow surface than most wide boots tested, though a bit weaker in flex than the 120 billing suggests.
They had few complaints though, citing a perfectly fine out-of-box fit that they said hedged a bit toward more medium fit tension. They noted that the toebox fit was a bit shorter than the average, per size, and looked forward to Vacuum molding to open that up a bit. The CF in the model name means Comfort Fit, indicating that the molding process will allow the forebody of the boot to expand but will not get any tighter in the forefoot—since not that many folks buying a wide boot are looking for a narrower fit there.
