Karhu is proud to introduce the all new Synchron 2020. The new shoe offers the latest in footwear advancements including an AeroFoam Nova midsole and Ideal Knit upper.
The Synchron 2020 is designed for the runner looking for maximal cushioning and plush underfoot feel without compromising an efficient transition.
The Synchron 2020’s AeroFoam Nova midsole provides a more luxurious cushioning experience than traditional EVA compounds found in most shoes. An internal stingray shaped composite fulcrum is dropped into the AeroFoam Nova midsole material which helps transition momentum through the gait cycle efficiently.
The Synchron 2020’s Ideal Knit mesh upper fits comfortably while securing the midfoot. The forefoot showcases the classic asymmetrical lace across the toe box to allow for micro-adjustments to the fit.
