The Puma Faas 500 S v2 Women's Running Shoe's improved upper design employs new tooling and innovative materials to deliver lightweight support and a bespoke fit. EVERFIT intersects the lacing eyelets and cinches the midfoot to apply an adaptive lockdown that can be altered by tightening the laces, whilst a lightweight, foamed AirMesh Plus material allows air to fully permeate the upper's interior. A series of reflective overlays straddle it to reinforce the shoe's structural integrity without adding undue weight and act to preserve the wearer's visibility in poor light. supportCELL employs a series of corrective elements to counteract overpronation and consequently encourage a more stable, biochemically efficient gait. A FAAS Engineered Stability Zone occupies the midsole and outsole layers of the shoe's medial side to encourage those with a flat arch and tendency to overpronate to adopt a more neutral transition from footstrike to toe off. A propriety FAAS Foam+ midsole compound affords the shoe's primary cushioning ability, delivering a springier feel, greater resilience and a formidably smooth ride. A lightweight, EverRide+ blown rubber outsole compound facilitates a more responsive toe off, whilst EverTrack technology augments areas that are particularly prone to wear and in turn increase the shoe's overall longevity.
