The Concept 10 GW is the men's model in Lange's comfort-first Concept line, built on a roomy 103 mm Comfort Last with a 100 flex and GripWalk soles. The Lyfran shell uses Dual Core construction, and a Suspension Blade adds smooth, progressive support through the turn.
The trade-off is that comfort and ease come ahead of race-boot precision. Skiers with narrow feet, or who want a stiff, high-performance flex, will be better served by a lower-volume Lange such as the Shadow.
It is a great match for recreational skiers with average to wide feet who want a boot that is easy to get on, easy to get off and comfortable all day. The Flex Adjust insert softens the flex by 8% if you want an easier feel.
Easy Entry and Exit channels and the Easy Closure System, a single buckle with a cable pulley on the lower shell, make it quick to close up. A thermoformable Comfort Fit liner, a Comfort Tongue and a 40 mm power strap finish the fit. Come see us for a boot fitting to get the size right.
We love the Concept 10 for skiers who want to spend more time skiing and less time thinking about their feet. It fits and feels as great as it skis.
Ski boots are sized in Mondopoint, based on the length of your foot in centimeters. The chart below is a general reference for converting between sizing systems.
This chart is not a fitting. The only way to know your ski boot size is to be fit in person, either with a Boot Fitting at our shop or from a professional fitting you have had elsewhere. Sizing, shape, and volume vary by brand and model, and a performance fit is snugger than your street shoe. Unworn boots can be returned under our return policy, but a boot that doesn't fit can be a big hassle for your trip if you haven't tried it on.

Conversions are approximate and can differ by half a size between brands.
Ski boots are built with one shell for each full and half size, so a 27 and a 27.5 are the same boot with a different liner or footboard. That is why sizes are listed together, like 27/27.5.
Very few models differ from this. Scarpa is the main exception, pairing sizes the other way (for example, 26.5/27 share a shell). When a model is sized differently, we call it out on that product's page.
