The 2021/2022 Lange RX 110 W was tested in the women’s All-Mountain Traditional medium category by the experts at America's Best Bootfitters, powered by Masterfit.
The Lange RX 110 W remains one of a small group of medium width performance all-mountain boots that remains at the very top of the heap year after year. Where a lot of brands’ medium-class boots fit more like wides to capture that out-of-box fit customer, the women’s RX line has always been about a blend of comfort with performance. There’s enough fit tension difference from the narrow RX LV to keep them from stepping on each other’s toes, marketwise, but no more—this is an all-mountain weapon that doesn’t hurt anywhere.
A few of our testers mentioned that the only place they noticed any excess space was up in the toebox, and everything else just fit. Upon closer evaluation of the fit-specific data for: toebox, forefoot, navicular, instep, heel, ankle and calf, the RX 110 W fit just to the snug-side of average within the medium width All-Mountain Traditional group with the exception of a slightly roomier-than-average instep and calf and the tightest heel and ankle pockets of the medium group. Testers unanimously approved of the new liner’s tongue construction, with a lot of comments about its higher level of cushioning and ultra-even fit against the shin coupled with a shared sense of surprise that it also seemed to energize the boot’s fore-aft energy and speed up communication between the leg shaft and the front of the ski.
Early turn engagement has been a positive characteristic of Dual Core plastics used in Lange models, and the new RBT technology (Reactive Boost Tongue) enhances this. The honeycomb polyurethane foam structure transmits more energy, earlier to the ski’s shovel upon flexion but without feeling too reactive or twitchy, testers said. The softer feeling shin and simultaneously stronger skiing the RBT tongue produced made for increased speeds through terrain and lumpified snow, testers reported, and they said that good skiers with chronic shin fit issues should put this boot at the very top of their lists. While the new tongue story was all about rebound, quickness and transmission of fore-aft movement, how did the RX W fare going side to side? Well, the edge power score was a perfect 5.00, so we figure it did okay.
Our testers are stoked on how Lange’s Cool Features are core boot elements rather than superfluous doo-dads. The Dual Core plastic injection process is legit—in our tests between non-Dual Core Lange models and newly released Dual Core versions of the same model (same mold, same liner) testers were instantly blown away by the different feel the internally sandwiched plastic densities gave to the boots. It was simultaneously better flexing but more powerful with a noticeably quicker turn entry and progressive transfer of energy to the ski. This new Reactive Boost Tongue (RBT) technology is similarly real—testers who knew nothing about the liner update came back from their on-snow tests raving about the tongue’s combined comfort and new level of energy release while skiing. Of course there’s cool stuff like GripWalk soles, dual screw style lateral cuff adjustment, a fat 45mm Velcro power strap and a Thinsulate laminate in the liner, but for our team that’s just the icing on a very tasty cake.
