Color/material: black mesh (polyester), microfiber, webbing, polyurethane, tph Design details: It's free, feels great, and facilitates your physical and mental wellbeing running is a life enhancer. So FitFlop set out to create the world's most comfortable running and exercise shoe. Biomechanically optimized for endurance running, eg suitable for 10K (but also for sports/gym or just upping everyday activity). Ultra light. High performance. Crafted in a soft stretchy mesh, engineered for high breathability at the vamp/toe and extra support at the sides/arch. 3D-printed detail and sole ombr effects/texture elevate the aesthetics. Padded on the collar/tongue. With easy foot entry thanks to a separate tongue/classic lacing, which also ensure the customized fit and security needed for running. All on a new 'performance' version of FitFlop's Neodynamic propulsion-plate midsole. Lighter. Even springier its innovative wishbone-shaped inner plate gives multi-directional propulsion, working with how the foot naturally moves (side to side as well as forward/back). More cushioned, in the highest-rebound impact-reducing EVA FitFlop has ever used. With an enhanced toe spring/heel kick for a smoother 'ride'. In a flexible yet stable women's-specific design, maximizing comfort and running efficiency (so you use less energy and can keep going longer). If the FFRunner doesn't get you running, nothing will. Note: These are engineered for a woman's anatomy/gait, not just a sized-down men's running shoe. Other features: Superlight flexible knitted tongue Anatomically contoured footbed for superb arch support & pressure diffusion Sole flares out at forefoot & heel to increase stability Light rubber outsole pods with extra grip & wear resistance for endurance running (grip suited to country paths/light trails) Outsole also has flex grooves to help feet move naturally & channels to reduce aquaplaning Contrast-color 'wishbone' propulsion plate visible on bottom of sneaker PU hotmelt & 3D-printed TPU detail (inc. reflective silver 'lines'/pull tab branding for when it's darker) Lace-up closure Light, slip-resistant rubber pods 1.5in platform Imported
