The womens Karhu Fusion has a larger Fulcrum 'rocker' type midsole and more support to help your mild to moderate overpronation. It is well cushioned and remains light whilst being durable for heavy road use. Karhu used big data from foot scans in their unique development of, among other areas, a more rounded forefoot that most brands.
Karhu say: "THE FUSION ORTIX BECOMES THE SECOND KARHU SHOE SHAPED BY FIT ID. THE UPDATES INCLUDE A SEAMLESSLY ENGINEERED MESH UPPER FOR A BETTER FIT. A NARROWER HEEL, REDUCED FOREFOOT VOLUME, AND FEWER OVERLAYS ENSURE THE FUSION ORTIX FITS THE AVERAGE SHAPE OF RUNNERS’ FEET. THE M-LOCK LACING CORDS HELP TO SECURELY WRAP THE MIDFOOT WHILE THE RESHAPED FOREFOOT PROVIDES COMFORT AT THE TOES. FEATURING A THREE-QUARTER LENGTH FULCRUM, THE FUSION ORTIX PROVIDES SUPPORTIVE GUIDANCE THROUGH THE GAIT CYCLE. BUILT ON A RELATIVELY LIGHTWEIGHT, YET DURABLE PLATFORM, THE FUSION ORTIX EXCELS AT PROVIDING JUST THE RIGHT AMOUNT OF COMFORT AND STABILITY."
