The men's Karhu Synchron 2.0 is a premium cushion daily trainer for neutral or mid to late-stage overpronators runners. The spring 2023 Synchron 2.0 received a complete update; a softer AeroFoam Nova midsole for the most comfortable run and redesigned upper, resulting in a premium supportive fit. Repositioning the stingray Fulcrum combined with a full contact durable outsole and a lighter midsole produces a soft, flexible, and stable ride with a smooth, supportive transition through the gait cycle. The Synchron 2.0 is ideal for longer runs and long days on foot.

New this season, the Synchron 2.0 is also available in a wide fit, KARHU calls this High Volume (HiVo).
