The Dolomite Rage X12 has all of the features while offering a bit of a higher volume fit and a flex index of 100. The Dolomite Rage 12 is the boot that does it all for the aggressive skier that loves all terrain and is willing to ski the mountain in all conditions. Dolomite is quite possibly the most underrated, high performance ski boot manufacturer in the world. Their ski boots, manufactured in Italy are fine tuned with precision details that only the Italians can master. This year, the Rage series is another step up for this past year’s release of high performance Rage ski boots and the Rage X12 will lead the pack.
