Marker Alpinist Free 11 — Featherweight Tourer with Freeride Backbone

Built for big days and bigger lines, the Alpinist Free 11 brings true touring efficiency without giving up downhill confidence. A new ISI “Intuitive Step-In” toe simplifies clipping in, while wider base plates at toe and heel boost power transfer on today’s broader skis. Add Active Length Compensation to maintain retention as the ski flexes, 35 mm of heel adjustment for multiple boots, and Performance Booster blocks under your heel, and you’ve got a minimalist tech binding that still loves to charge.

Why you’ll love it

• Easy, reliable step-in — ISI Toe with a rubber stop pad and a wider platform makes pin engagement quicker and more intuitive.

• Stronger ski feel — Wider base plates (toe & heel) spread loads for better edge hold and power on wider skis.

• Stays engaged through flex — Active Length Compensation lets the heel track move as the ski bends for consistent release/retention.

• Dial your leverage — Performance Booster (3 interchangeable blocks) sits under your boot heel to increase power transfer on the down.

• Efficient climbs — 0° / 5° / 9° climbing positions keep ascents smooth and legs fresh.

• Real-world adjustability — 35 mm of heel length adjustment accommodates quiver boots or shell punches.
