Lange Ski

Frequently Asked Questions

• How do I choose the right Lange last and flex for my foot shape and skiing ability?

  Match the last (width) and flex to your foot and skill: Comfort Last (about 103mm) and Comfort Volume suit wider or comfort-oriented feet, while 97/99/100/102mm lasts are narrower for precision and racing. Flex ranges from ~75 (forgiving beginner/intermediate) to 100–120+ (advanced/powerful); a 103mm/90 flex is a common combo for beginners seeking comfort. Measure your foot, try on for heel lock and toe room, and use Lange’s thermoformable liners to dial fit.
• How does the Concept series compare to Lange’s RS/World Cup race lineup?

  Concept models (Concept 9, Concept 7.5, Concept 11/12 BOA® and women’s Concept BOA variants) prioritize all-day comfort, easy entry, BOA® options, and a softer flex profile for recreation. The RS/World Cup lineup (World Cup RS ZSoft+, RS 120 SC LV) uses Dual Core and race-focused shells, narrower lasts and stiffer flex for maximum power transfer and responsiveness. Choose Concept for comfort and ease, RS/World Cup for on-piste precision and high-performance racing.
• Which Lange models and sole types are best for backcountry touring versus resort all-mountain skiing?

  For backcountry/touring choose Lange models with ultralight constructions like Dual Core Light or Superleggera and Vibram®/ISO 9523-compatible soles for walkability and crampon/binding compatibility. For resort all-mountain pick Concept or mid/upper-level RS models with GripWalk® or solid alpine soles for better traction on bootpacks and secure alpine binding interface. Consider flex and weight trade-offs: lighter touring boots favor uphill efficiency, while heavier stiffer boots favor on-piste power.
• How does BOA® closure on Lange boots compare to traditional aluminum buckles?

  BOA® dials (available on Concept 10.5/8.5/9.5 BOA® and Concept 11/12 BOA® models) provide quick, micro-adjustable, even tensioning that’s handy for on-the-go tweaks and sensitive instep control. Traditional aluminum buckles give more direct mechanical clamping and are often preferred on stiffer RS/race shells for precise power transfer. Choose BOA® for convenience and even fit; choose buckles when you need maximum adjustability for high-power skiing.
