The new Flyhike Blast2 features K2's proprietary elastic foam called ‘FLYFOAM’ and injection-molded ‘FLEXIBLE CLEAR SHANK’ on the sides, providing excellent cushioning and adding propulsion during walking.


In particular, the FLYFOAM applied to the midsole increases the rebound elasticity rate by more than 20% compared to previous models, maintaining elasticity and cushioning even after long periods of wear. The flexible shank on the sides adapts flexibly to foot movements, adding propulsion for a comfortable stride.


Additionally, the ‘GORE-TEX Invisible Fit’ technology offers outstanding waterproof and breathable functions, as well as a comfortable fit and feel similar to wearing regular running shoes. These shoes can be worn lightly and comfortably anytime and anywhere, whether for light hiking, travel, or daily life, regardless of outdoor or urban settings.


Furthermore, to ensure comfort during long walks, the midsole is designed with an arch support structure that helps prevent the arch from collapsing while walking. The outsole uses X-Grip optimized for granite, which accounts for over 80% of Korea’s terrain, providing excellent traction and durability.



Dongjun Shin, Director of K2 Footwear Planning Team, said, "With the autumn season marking the start of active outdoor activities, we have launched the Flyhike new product with outstanding functionality and versatility. We hope you experience comfortable steps with the Flyhike series, K2’s representative footwear line that incorporates innovative technology and design."
