Upper: Open face air mesh vamp is lightweight and breathable with no abrasion hot spots. HF welded logo is lightweight and low profile for a performance feel and a great look without added weight. Padded heel collar and padded air mesh tongue for maximum breathability and comfort. A supportive top stitch detail throughout the vamp is breathable with a lockdown secure fit. HF (High Frequency) welded toe guard is lightweight and provides durability and protection during toe off.

Midsole: Precision engineered three part molded EVA with tuned durometers provide an extremely responsive and lightweight ride ensuring the quickest transition available. The asymmetrically designed Fulcrum in the Flow is the firmest and most responsive with a durometer of 77 for maximum momentum. EVA around the fulcrum has a durometer of 53. A removable high performance polyurethane Ortholite sockliner provides excellent moisture management and durable cushion with a great step in feel. Low density EVA forefoot insert in an hourglass shape provides anatomically correct forefoot cushioning during the propulsion phase. Fulcrum Technology turns energy and pressure into forward momentum. Through the three phases of the gait cycle, the Fulcrum is designed to convert energy and pressure into forward momentum by transitioning the foot from heel to toe quickly and efficiently while the body stays balanced throughout the stride. Fulcrum reduces wasted vertical forces, speeding up the time the heel is on the ground. It provides a natural ride throughout the gait cycle promoting the foot's natural abilities. The foot follows the path of least resistance so large shifts of pressure to the outer and inner edges do not occur. During heel strike, the platform, extending back from the Fulcrum points, absorbs the force of heel strike loading the Fulcrum with energy. During the gait cycle, the center of pressure is balanced as it travels from the landing platform through the Fulcrum points, creating a natural path for the foot. The asymmetrical Fulcrum points allow for balanced heel strike and create the transition from the braking phase to the propulsion phase. Lightweight, low profile Fulcrum has been engineered for maximum momentum. California slip lasted for stability and comfort. The upper is stitched around an EVA board and directly attached to the midsole.

Outsole: Compression molded outsole with anatomic flex grooves provides superior durability, traction and cushion. High abrasion compression rubber with T-lugs provides superior traction and piston cushioning.
