The new updated Ikoni gets lighter and more cushioned with a softer step-in feel and a more balanced, featherlight ride. Over 2 million 3D foot scans have allowed Karhu to fine tune the fit and performance of the Ikoni. An anatomical lacing system helps to dial in the fit, while a half-length fulcrum and propulsion unit contribute to a quick, light turnover. This is an everyday trainer that is good for quick tempo runs, as well as longer efforts. If you are a fan of Karhu, you will love the Ikoni 2021. If you haven’t tried Karhu in awhile, this is a shoe that will impress.
