The smooth and supremely cushioned KARHU Ikoni 3.0 is purpose-built to keep you moving forward in balanced comfort all day long. Whether you're racking up easy miles or mixing in some uptempo efforts, the Ikoni 3.0 shines thanks to its plush AeroFoam cushioning and signature Fulcrum that stabilizes your stride and propels you forward with a guided, rocker feel. The result is a luxuriously soft yet responsive ride ideal for everyday training. Details: Upper: A supple, brindle patterned IdealKnit mesh upper and flared heel counter gives you a secure lock-down and instant step-in comfort. It has an accommodating shape and lightweight design, thanks in part to millions of fit id® scans from Fleet Feet. Midsole: Karhu's signature Fulcrum technology uses a stabilizing midsole geometry that leverages your body's natural motion to propel you forward. It is then wrapped in a plush bed of AeroFoam cushioning for an effortless flow from landing to toe-off. Outsole: To improve stability, traction and durability, the outsole has more rubber coverage and a newly added deflection channel.
