CONTROL FIT TECHNOLOGYThe combination of shell last and liner execution to fit more feet accurately and comfortably. Control Fit shell technology: Lange scanned the feet of 20,000 skiers from around the world with a new, state-of-the-art 3D imaging system. Through this analysis, Lange learned that most skiers benefit from a wider, asymmetrical toe box combined with a slightly narrower, more articulate ankle pocket than is found in most of our competitors products. We believe the combination of more room in the forefoot and more accuracy in the ankle delivers the best of both worlds: comfort and performance. Control Fit liner technology:Lange incorporates the features, practical techniques and attention-to-details that boot-fitters have used for years to accommodate the hard-to-fit ‘deal breakers’ that have traditionally impeded fit and sales. As all boot-fitters know, the difference is in the details, and our details must be seen to be believed.MONO INJECTION WITH SOFT INSERTThe basic monoinjected structure provides the highest performance and is easy for bootfitters to work with while the soft instep insert guarantees easy entry and exit.NATURAL SKI STANCELange employs the unique Natural Ski Stance that allows skiers to stand a little straighter for more efficiency and less fatigue.ONE PIECE COLLARThe continuity of the collar material enhances the fit of every calf dimension and guarantees the right rear support.POWER WEDGE TONGUEBetter wrapping of upper leg, enhances precision and sensitivity by eliminating any gap between shin and tongue.QUICKSET RATCHETAutomatic and fast adjustment of the ratchet position to fit every calf dimension.READY FOR HEATINGMost of Lange liners are ready to mount optional external heating systems (not included).THERMO FIT RL1Thermo fit liners: the RL1, RL2 and RL3 liners are thermomouldable liners. They offer an increasing foot Retention Level from 1 to 3 (the highest retention) to meet the right balance of performance and comfort different skiers may need.XL BUCKLESExtra Long buckle lever, reduces the effort to buckle and unbuckle.
