While the boot's name, Pure Pro 100 has been around for a few years, this season marks a completely new shell and cuff design (new molds) and all-new liner to suit. Testers loved all the changes and also what didn't change. The 100 mm Pure boot was known for its easy going, comfortable fit with lots of faux fur and a little extra toe room, all of which tended to keep it just out of the tip top tier in the performance score categories. The new Pure Pro 100 has kept a lot of the easy: easy on and off, easy to fit without hot spots, easy to stay balanced. But it has upped its game in terms of how its fit is more closely matched to anatomy rather than reliant on liner cushioning. It no longer fits longer--at least not any more than other models in the group. And it transmits movements to the ski with less slop in the liner linkage--testers said that the liner felt married to the interior of the shell for a zero-delay feel for the snow.
