ISPO Award Winner 2024: Constrictor Warm SC GTX by Viking

The Constrictor Warm SC GTX by Viking Outdoor Footwear is designed to tackle extreme winter conditions with ease. Engineered for both outdoor enthusiasts and professional users, this high-cut winter boot incorporates groundbreaking Solarcore technology. Inspired by NASA’s Aerogel insulation, Solarcore is a proprietary material that provides exceptional thermal efficiency even under compression. Unlike traditional insulation, it achieves high warmth without bulk, making it ideal for demanding cold-weather activities. Adding to its functionality, the boot features a PFAS-free GORE-TEX membrane made of ePE, ensuring waterproofing and breathability. This combination of technologies keeps feet warm, dry, and comfortable in deep snow and frigid temperatures. 

To ensure stability and durability on snow and ice, the Vibram MegaGrip outsole with Traction Lug offers industry-leading grip, while a stability plate in the midsole enhances comfort. Reflective panels on the lateral sides provide visibility in low-light conditions, improving safety. “With our close collaboration with GORE and Vibram, this boot exemplifies Viking’s commitment to creating advanced footwear by leveraging our trusted partnerships,” says Ludvig Fauske-Palmér, Product Manager at Viking. 

The Constrictor Warm SC GTX recently earned an ISPO Award, underscoring Viking’s reputation as a leader in technical footwear. “With a heritage spanning over 100 years, this award confirms that we remain at the forefront of innovation while inspiring us to pursue future projects that integrate cutting-edge technologies,” says Fauske-Palmér. Solarcore, a key highlight, uses NASA-inspired Aerogel technology, offering unmatched insulation without the weight or bulk. This zero-bulk approach not only improves performance but also expands its utility across various fields like aerospace, defense, and apparel. 

Sustainability is another hallmark of the Constrictor Warm SC GTX. Viking has prioritized recycled materials, including recycled EVA for the midsole, as part of its effort to create more eco-conscious products. By balancing high performance with environmental considerations, the brand sets a new benchmark for sustainable outdoor footwear. 

Viking Outdoor Footwear’s Constrictor Warm SC GTX is not just a winter boot—it’s a testament to over a century of expertise in crafting footwear for all conditions. Combining state-of-the-art materials and sustainable practices, this ISPO-winning product continues Viking’s legacy of pushing the boundaries of innovation.
