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.

Technologies Karhu Synchron 2.0 HiVo:
-Anatomical lacing system
-Full-length Fulcrum
-IdealKnit
-Ortix Fit
-AeroFoam Nova midsole
-M-Lock
-Open-cell foam insole
