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.
