- Blizzard GTX is La Sportiva’s first trail running shoe that is designed for extreme use on slippery and icy terrain. It features a water-resistant gaiter and waterproof lining that keep the foot warm and dry in deeper snow. 

- This winter-oriented running shoe utilizes the FriXion® Blue rubber compound for maximum grip and durability in the most severe conditions. The AT Grip Fixed Spikes infused in the outsole ensure stability and propulsion. 

- The shoe also uses the Gore® Flex Construction membrane technology. It is a durable waterproof material that offers optimal protection against the elements. 

The La Sportiva Blizzard GTX follows the standard running shoe length to accommodate users with narrow to wide foot volume. Providing a customized fit is the lacing system that allows the user to easily adjust the tightness around the shoe. Another component that affects the fit of the shoe is the Ortholite® sockliner that offers a more comfortable in-shoe feel. 

Runners are welcome to get a pair in their usual sizing preference, though it is recommended to fit the shoe first or check the user feedback about sizing to ensure a comfortable fit. 

Providing supreme traction is the FriXion® Blue rubber incorporated in the outsole unit. FriXion® Blue is a soft, long-lasting compound that offers excellent grip on a variety of surfaces. 

Infused in the outsole are the AT Grip Fixed Spikes, which provides a firm grip on icy and slippery surfaces. The spikes are specifically designed to ensure stability and efficient propulsion. 

The Blizzard GTX utilizes an ethylene-vinyl acetate (EVA) foam that offers firm yet flexible cushioning. Other popular running shoes, such as the New Balance FuelCell Rebel and Altra Lone Peak 4.0, also has this feature. This lightweight midsole material lessens the impact during the landing phase of the gait cycle, providing a softer and smoother running experience. The EVA foam is also resistant to abrasion, allowing the midsole cushioning to maintain the same features and form for the entire running duration. 

The Ortholite® sockliner is an additional layer of cushioning that is positioned beneath the foot. It provides additional protection while improving the overall fit. 

The Gore-Tex material is integrated into the La Sportiva Blizzard GTX. This material keeps the shoe waterproof and highly flexible. It also equipped the shoe to withstand extreme weather conditions and keep the foot dry and comfortable.  

The stretch sock-shield gaiter that wraps the foot is also water-repellent. It provides protection against mud, stones, and snow. 

This La Sportiva running shoe features the single cord lacing system with an integrated lace pocket. The lacing system allows perfect wrapping and volume regulation. The high-frequency Fusion Gate structure that connects to the lacing system also offers additional support and a more customized fit

Reflective details are also integrated into the shoe upper. These add ons are designed to keep the runner visible in extreme conditions or during low light runs.
