Review: Look HT Radical 10

The Look HT Radical 10 is a tech/pin touring binding aimed at skiers who want dependable downhill performance and simple, pole‑friendly transitions. With a 4–10 DIN range, integrated brakes, and a heel riser you can flip with your pole (no heel rotation needed), it’s a practical, confidence‑inspiring choice for general backcountry use.

• Ski tourers prioritizing reliability and ease of use over shaving every gram.
• Lighter to midweight riders or anyone whose proper setting falls at or below DIN 10.
• Backcountry/sidecountry skiers who value an integrated brake and straightforward operation.

• Uphill: The tilt‑up climbing bar is quick to engage with a pole, keeping transitions smooth on rolling terrain. It strikes a nice balance between simplicity and function.
• Downhill: Versus ultralight pins, the HT Radical 10 feels more planted and predictable. The DIN to 10 suits most touring skiers; very heavy or ultra‑aggressive riders may want higher release ranges.

• Type of binding: Alpine Touring (Tech/Pin) — Built for efficient climbing with pin inserts while keeping weight low.
• DIN value: 4-10 — Adjustable release (vertical/lateral) for controlled safety in a fall.
• Elastic travel: ~10mm (not officially specified) — Provides compliance to reduce unwanted pre‑release; verify proper gap/travel at install.
• Brake width: 82mm, 92mm, 100mm — Choose a brake 5–15 mm wider than your ski waist for clean clearance.
• Weight: 1040g per pair (with brakes); ~520g per binding — Not ultralight, but sturdy and tour‑friendly.
• Compatibility: ISO 9523/tech inserts — Requires boots with metal tech fittings; non‑tech alpine soles are not compatible.
• Materials: Aluminum alloy, steel pins, engineering plastics (POM) — A proven mix for durability without excess weight.

• Integrated ski brake in multiple widths.
• Easy step‑in with Look’s clear heel adjustments (two screws set vertical/lateral release per Look procedure).
• Pole‑operable climbing bar; no heel rotation required to change riser height.
• 25 mm heel length adjustment for boot‑sole length changes, sharing, or rentals.
• RTL variant available (HT Radical 10 RTL).

• Marker Alpinist 10: Lighter and often sold brakeless (brakes optional), but with a more minimal “feel.” The Look trades a bit of weight for a burlier ride and integrated brakes.
• Dynafit Radical: Similar weight/intent. The Look holds its own in downhill confidence; choice may come down to step‑in feel and local service.
• ATK Raider 10 / Salomon MTN: Typically lighter and pricier or with different riser ergonomics. The Look is a straightforward, value‑minded workhorse.

• Heavier than the lightest pin bindings.
• DIN tops out at 10; big/aggressive riders may want more range.
• Elastic travel not published; precise mounting and checks are important.
• Brake options up to ~100 mm won’t fit the widest powder skis.

Good to know

Have a certified technician mount and adjust the binding per Look’s technical manual.

Key takeaways

• Confidence over grams: more composed than minimalist pins.
• User‑friendly: pole‑flippable riser and integrated brakes.
• Best for DIN ≤10 tourers seeking a stable, simple setup.
• Solid value for backcountry and sidecountry use.

Q: What boots work with the Look HT Radical 10?
A: Touring boots with metal tech inserts (ISO 9523) are required. Alpine soles without tech inserts are not compatible with this tech binding.

Q: How do I pick the right brake width?
A: Choose a brake 5–15 mm wider than your ski’s waist. For example, a 90 mm waist usually pairs well with a 92–100 mm brake.

Q: Can I use it for resort days?
A: For occasional in‑bounds laps, yes, but it’s primarily a touring binding. Frequent, aggressive resort skiing is better served by a hybrid or alpine binding with higher elasticity and DIN.
