Review: Look ST 10

Overview

The Look ST 10 is a lightweight tech touring binding built for efficient ascents and confidence on the way down. With a 4–10 DIN range, about 10 mm of elastic travel, and multiple brake widths, it strikes a practical balance of weight, reliability, and ease of use for backcountry skiers.

Key takeaways

Light yet solid: roughly 700–740 g per pair (with brakes) for big vert days.
DIN 4–10: well-suited to lighter to medium-weight skiers and moderate descents.
10 mm elastic travel: helps absorb shocks and maintain consistent release.
Brake options: commonly 92 or 105 mm; choose ~10–15 mm wider than ski waist.
Easy step-in: guided tech toe with supportive towers and sensible heel risers.

On-snow performance

Uphill efficiency is excellent—low mass, simple transitions, and dependable heel lifters. On the descent, the ST 10 feels composed for its weight class, with predictable release behavior and adequate power transfer for touring missions. It’s not a resort charger, but for typical backcountry lines it’s trustworthy and calm.

Specs and what they mean

Type of binding: Touring (Tech/Pin) – frameless, pin-insert design prioritizing uphill efficiency and low weight.
DIN value: 4–10 – tuning range for lighter to average skiers; ideal for classic ski touring.
Elastic travel: approx. 10 mm – length compensation for ski flex and impacts, supporting consistent release.
Brake width: 92 mm, 105 mm – pick a brake ~10–15 mm wider than your ski’s waist.
Weight: 700–740 g/pair (≈350 g/binding) – light enough for long days without feeling flimsy.
Compatibility: Tech-pin boots with ISO 9523 touring soles (inserts required); not for alpine soles without inserts.
Materials: Aluminum, stainless steel, high-tech polymers – balanced for stiffness, durability, and low weight.

Comparisons

Dynafit ST Rotation 10: similar target skier and feel; the Look matches its smooth step-in and elasticity with comparable overall weight.
Marker Alpinist 10: lighter, especially brakeless, but offers less elastic feel; the Look provides a touch more composure on the descent.
Salomon MTN Pure: close in weight and intent; the Look wins on step-in guidance and brake options, while the MTN is prized for simplicity and stiffness.
Fritschi Tecton 12: heavier with stronger downhill power; better for aggressive skiing, less ideal for long climbs.

Mounting and setup

Have a qualified tech mount and set DIN. Confirm your boots have tech inserts and choose the right brake width. Set toe/heel gaps and forward pressure exactly to spec for best release performance.

Potential drawbacks

DIN tops out at 10, which limits heavier or very aggressive skiers.
Not the absolute lightest in class versus the most minimal race/fast-and-light options.
Less ideal as a pure resort binding; it’s designed for touring efficiency.

Verdict

The Look ST 10 is a well-executed tech touring binding for skiers who value low weight, reliable release, and friendly handling. It climbs quickly, descends confidently, and offers useful elasticity and brake choices. Heavier or hard-charging riders might prefer a burlier or hybrid option, but for its intended touring role, the ST 10 is an easy recommendation.

Frequently asked questions

Q: Who is the Look ST 10 for?
A: Ski tourers who prioritize low weight, efficient climbs, and reliable downhill performance. Its DIN 4–10 range suits lighter to average skiers.

Q: What brake width should I choose?
A: Typically 10–15 mm wider than your ski’s waist. For example, a 92 mm brake for 80–85 mm skis, or 105 mm for 95–100 mm skis.

Q: Is the ST 10 good for resort use?
A: Occasional resort laps are fine, but it’s built for touring. For heavy resort use and aggressive skiing, a burlier alpine or hybrid binding is better.
