Reliability Meets Sleek, Modern Updates in Karhu’s Newest Edition of Its Ultimate Workhorse Shoe
The Ikoni has become known as one of the most versatile and dependable daily trainers in Karhu’s line-up. The newest edition incorporates everything you loved about the previous version, such as a balanced ride and stable feel, while adding some significant tweaks to improve overall fit, feel, and support.
Underfoot, the Ikoni 3.5 features Karhu’s trusted signature AeroFoam cushioning. With a moderate stack height of this balanced, plush Nitrogen-infused foam, you can expect soft, protected landings without sacrificing energy return and ground feel.
Embedded in this plush midsole, you’ll find a propulsive Fulcrum unit to balance out the softness and ensure exceptional forward momentum through any type of run. This unique Fulcrum rolls you through every stride, all while adding some stiffness, rebound, and stability. Paired with a wide, stable midsole platform, this midsole construction is guaranteed to keep you feeling confident and steady throughout all your daily miles.
While the midsole unit is very similar to previous iterations, some of the biggest upgrades can be found in the upper construction wrapping the foot. The IdealKnit mesh upper has been refined to offer even more stretch, breathability, and comfort around the top of the foot. The anatomical lacing and M-lock design work with this improved upper to provide a secure lockdown and superior support.
Last but certainly not least, the reinforced rubber outsole ensures maximum grip and durability so you can enjoy these features throughout all of your daily miles without worrying about early wear.
