The Karhu Ikoni Trail trainer lets you tackle any adventure off-road. This running-style outdoor shoe is designed with a slightly higher forefoot volume to allow toe splay and lasting comfort on long trail runs. The cushioned AeroFoam midsole combined with the underfoot protection provides unparalleled comfort while still having a solid ground feel. The unique ascending Fulcrum cradles the foot and propels you forward for an efficient ride on the flats as well as up and downhill.
