Together with our partner, Fleet Feet, Karhu gathered and analyzed 100,000 foot scans in order to find the optimal fit for the Ikoni Ortix. A ½ length Fulcrum midsole makes this a cushioned shoe on impact and directs all forces forward. The Ortix midsole provides arch support, aligning the foot and reducing pronation and foot fatigue. Our new Aero Foam midsole and Flight Deck insole provide our smoothest transition yet.
A 1/2 length Fulcrum unit combined with a full contact landing platform is able to reduce pronation upon landing, while a flexible forefoot provides a natural ride on this neutral model.
Our Triple Bio Action midsole features a third layer at the bottom of the Fulcrum for highly efficient propulsion.
This model provides slightly more flexible forefoot than the Karhu Fusion, Synchron, Fast or Strong. This model suits a normal volume foot, where as a higher volume foot might be better suited in a Fusion or Synchron Ortix, or perhaps go up up ½ in the Ikoni. Weight Size 10 US 300G/10.6 Oz.
