Harsh winter cold demands reliable warmth, and now we're raising the bar! Solarcore® is a groundbreaking thermal insulation system that delivers unmatched warmth and performance – without the bulk, weight, or stiffness.
Viking Solarcore® is an advanced insulation technology developed for extreme winter conditions. The ultra-thin Solarcore® membrane draws inspiration from NASA-developed aerogel technology, keeping your feet warm and comfortable as temperatures drop.
01 — Built for movement
When you wear footwear with Solarcore®, your foot naturally creates pressure against the ultra-thin Solarcore® membrane. This pressure activates the insulation, making it even warmer as you move.
02 — Ultra-thin membrane
The Solarcore® membrane keeps your feet warm without compromising flexibility or freedom of movement.
03 — Reliable grip
A rubber outsole with deep lugs provides reliable traction on challenging terrain.
The 2025 launch earned an ISPO Award for its innovative approach to insulation and heat retention. The boots were also selected by Nåva Space for testing in the European Space Agency’s laboratories, contributing to research and development for future space exploration. In addition, their technology supported the creation of a new European spacesuit concept designed for spacewalks, paving the way for a future pressurised version.
Good enough for spacewalk, good enough for your day out in the cold?
