The liner that takes the shape of your foot as you wear it

Protection given down to −40 °C / −40 °F*. The Yoho bets on mobility: 1.99 kg (4.38 lb) a pair for a mid-height 23.5 cm (9.25 in) upper, a Superlite™ Blend shell and a LiteGrip™ Blend base with a Polar Rubber® outsole. The Active-Fit liner moulds to body heat and ends up following the shape of the foot. A velcro tab at the heel keeps it secured to the shell, with toggle speed lacing and pull loops at the back and on the tongue. Snowshoe ready, vegan build. EUR sizes 39 to 48.5.

The Grand-Froid expert view

A removable liner has one drawback everybody who owns a pair knows about: it comes away with the foot when you pull the boot off, and it has to be pushed back in every time. A velcro tab at the heel keeps it secured to the shell — the boot comes off in one movement, the liner stays where it is, and it only comes out in the evening to dry. The other point plays out over time: the liner thermoforms to body heat, which means it feels firm for the first few days and then hollows out at the pressure points. A boot that comes round to the shape of the foot rather than the other way about.

What is it for?

Built for moderate activity in sub-zero cold, on frozen or snow-covered ground.

  • Snowshoe walking: the build takes the binding, and the vamp clip takes the accessory
  • Winter walking: frozen paths, packed snow, outings of several hours
  • Winter in town in a cold climate: commutes, waiting about, the light boot you keep on from morning to night
  • Clearing snow and jobs around the house: digging out the drive, fetching logs, short tasks in hard cold
  • Driving and journeys by vehicle: the shaft height and the weight are no trouble behind the wheel
  • Travel in cold countries: Quebec, Finland, Iceland, when weight counts in the case

Thermal protection

The Active-Fit liner goes after warmth with as little material as possible. Against the foot, the Thermawick™ lining clears perspiration and evens out temperature; the thermoformable B-Tek™ Foam moulds to the shape of the foot; B-Tek™ Lite, a proprietary aero-insulation blend, reaches the insulating volume of air on reduced thickness; and the four-channel hollow fibre B-Tek™ Heat completes the volume while staying breathable. On the outside of the liner, a PolyNylon blend carries the durability without adding weight, and Diamond Net closes off the passage of air. Under the foot, the Superlite™ Blend shell and the LiteGrip™ Blend base cut conduction with frozen ground, the main route of heat loss when standing still. One point decides the outcome: the sock must never grip, because any compression crushes the air and removes the insulation.

Size guide

This model runs small: take the size above. The liner thermoforms after a few hours of wear: it feels firm for the first few days. Wear a thick sock with no tightness.

Composition

⚠ [DATA MISSING] — The upper composition is contradictory at source: the technology sheet states artificial leather, the care instructions mention nubuck and nylon. Material split to be confirmed before publication.

  • Upper: artificial leather and nylon, with nubuck sections
  • Shell and base: Superlite™ Blend and LiteGrip™ Blend, B-Tek™ Dry waterproofing
  • Outsole unit: Polar Rubber®
  • Liner — inner layer: Thermawick™, moisture wicking and thermal regulation
  • Liner — structure: thermoformable B-Tek™ Foam, B-Tek™ Lite aero-insulation and four-channel hollow fibre B-Tek™ Heat
  • Liner — outer layer: PolyNylon blend, breathable durability
  • Liner — air management: Diamond Net windproofing
Care & Durability
  • Nubuck: wipe with a damp cloth to remove excess dirt, then dry in open air
  • Nylon sections: hand wash in warm water, with a mild detergent for stubborn dirt
  • Rubber base: wipe with a damp cloth
  • Take the liner out every evening and let it dry in open air
  • Dry away from any direct heat source: excessive heat distorts a thermoformable liner
  • Store somewhere dry and ventilated, laces loosened

Why choose the Yoho?

Because it looks for warmth through construction rather than bulk: the B-Tek™ Lite aero-insulation reaches the volume of air on less material, the Superlite™ Blend shell brings the pair down to 1.99 kg (4.38 lb), and the Active-Fit liner comes round to the shape of the foot over successive outings. Added to that are two details in use: the velcro that holds the liner in place and the gaiter clip at the vamp.

A light winter boot is judged at the end of the day, when you have not felt it

* Indicative temperature. Perceived warmth varies with activity, body type, humidity, wind, length of exposure and the socks worn.
