Advanced technical approach shoe with Arc'teryx Adaptive Fit technology, air permeable comfort and a seamless thermolaminated upper. With an advanced design specifically geared for technical approaches and day hikes on mixed terrain, the Acrux FL combines Arc'teryx Adaptive Fit comfort, the durability of a seamless thermolaminated upper, and a unique outsole designed for agility, grip and support. The stretch monomesh Adaptive Fit liner forms to the foot for an exceptional fit with no pressure points. Highly air permeable, it delivers the ventilation required for long days in warm, dry conditions. The quick drying single piece upper uses seamless thermolaminated construction for elevated abrasion resistance and irritation free performance. Designed with VibramAR, the Arc'teryx Approach Outsole combines the grippy surefootedness of a climbing shoe with the stability and rolling stride of a hiking sole. Cushioning comes from the injected EVA midsole that is specifically moulded for stability and impact protection on varied terrain.
