A counter-directional T-lug design on the soles of Karhu Flow Trail running shoes adapts to both uphill and downhill running for a more versatile experience on a greater variety of surfaces. The functionally designed upper features a waterproof mud guard that protects your feet from the elements in addition to adding a unique style element.

Upper: Anatomically sculpted air mesh provides maximum ventilation combined with a highly abrasive and water resistant side vamp wall. A gusseted tongue is anatomically mapped around the instep and features a soft touch logo top that keeps dirt out. Welded eyelets and a reinforced forefoot weld ensure a proper fit by resisting uphill and downhill pressures. The dual-pronged memory foam heel collar offers enhanced comfort. Moisture wicking collar liner helps keep you dry and comfortable. Lateral fulcrum reflectivity give essential visibility.

Midsole: Precision engineered compression molded EVA midsole with tuned durometer hardness provides optimum forward efficiency. EVA padded lasting board locks the heel comfortably in place. Directly placed EVA fulcrum propels runners onto their forefoot and into toe-off more efficiently, reducing breaking forces and heel drop into the landing phase. The removable compression molded EVA insole gives arch support, moisture management, and step-in feel.

Outsole: Expanded zones of compression rubber in a counter grip pattern with a center compression channel provides lightweight, uphill and downhill grip for back country conditions.
