The men's Karhu Synchron 2.0 HiVo 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.    

The KARHU Synchron 2.0 HiVo version is more than just a "wide" as it accounts for feet with higher insteps, greater instep girths, and flat and all-around larger-than-average feet.

-Anatomical lacing system for micro-adjustments 
-Full-length Fulcrum for a stable ride
-Soft & cushioned AeroFoam Nova midsole 
-IdealKnit mesh construction for breathability and support 
-Seamlessly engineered upper 
-Open-cell foam insole for a plush feel
