Ski bindings explained

Brake width, release value and boot soles: everything you need to pick the right binding.

Winter Sportz buying guide · updated 9 October 2026

Quick answer

Choose a binding whose brake is as wide as your ski's waist or up to about 15 mm wider, whose DIN range includes your release value, and that fits your boot sole (alpine, GripWalk or touring). Have it mounted and set to ISO 11088 by a technician.

What a binding does

It holds your boot firmly while you ski and releases it in a fall to protect your knees. The release value (DIN) sets how much force it takes to release.

Brake width

The brake stops a released ski. It must be at least as wide as the ski underfoot and no more than about 15 mm wider, so a 100 mm ski needs a 100–115 mm brake.

Release value (DIN)

Your DIN depends on weight, height, age, boot sole length and skier type (1 cautious, 2 average, 3 aggressive). It is set according to ISO 11088; we do it for you when we mount the binding.

Boot sole norms

  • Alpine (ISO 5355): classic ski boots
  • GripWalk: rubber soles that walk better; needs a GripWalk-compatible binding
  • Touring (ISO 9523) and tech inserts: for touring and hybrid bindings
  • Multinorm (MN) bindings accept several sole types

Alpine, hybrid or pin?

Alpine bindings are for resort skiing. Hybrid bindings such as the Shift or Duke PT walk uphill and ski like an alpine binding. Lightweight pin bindings are for touring. Shop ski bindings.

Frequently asked questions

Short answers to what skiers ask us most. Still unsure? Ask us.

How do I know my DIN setting?

It is calculated from your weight, height, age, boot sole length and skier type according to ISO 11088. Have a technician set it; we do it when we mount your binding.

Can any binding fit any ski?

Only if the brake width matches: at least as wide as the ski underfoot and no more than about 15 mm wider. The binding must also fit your boot sole.

What does GripWalk compatible mean?

The binding works with GripWalk boot soles, which have a rocker and rubber tread for walking. Check compatibility before mounting.
