Karhu is more than just a shoe - it's a science. These shoes have been worn by some of Finland's most legendary runners, winning Olympic medals, Boston Marathon races and everything in between. Their unique Fulcrum technology was created in 1987 and then tested and developed at Jyväskylä University in Finland and Iowa State University in the USA. Fulcrum? It's a technology that reduces unnecessary vertical and horizontal movement, which helps you land and push off with a better body position and rotation. Simply put - Fulcrum helps you move forward easier, faster and more efficiently. The fact that the shoe looks good in everyday life is just a plus.
