The light, durable Acrux FL is specifically designed for warm weather hikes and approaches on varied terrain. The highly air permeable micromesh Adaptive Fit liner stretches around the foot for a custom fit, and offers a high level of ventilation. Made from a quick drying PU coated nylon textile, the upper is a seamless single piece utilizing thermolaminated construction to create a smooth, uninterrupted surface that's lighter in weight, exceptionally abrasion resistant, and not subject to failure at seams. The injected EVA midsole is designed and moulded to work in tandem with the outsole for superior braking on descents and agility on the move. Three dimensional toe and heel caps protect the foot and further extend the Acrux FL's durability. The design is women's specific.
