- Size 8.5 -“The Rundown Made for those who run but don’t just run, the lightweight Cavu offers a versatile running shoe with a bold and simple look. Cavu’s lower midsole features our much lauded “intelligent” PROFLY™ cushioning — softer in the heel for shock absorption and firmer in the forefoot for propulsion. That responsiveness is further enhanced by the outsole’s zonal rubberized foam. Employing a super breathable engineered mesh upper, this shoe really disappears on the foot and it delivers a smooth, light ride. With Cavu, it sure looks like clear skies ahead.” - BEST FOR: Trail FEATURES: Lightweight, open engineered mesh offers a comfortable fit and optimal breathability Thin lycra comfort-fit bootie underneath the engineered mesh provides a seamless layer next to the skin Internal reinforcements for invisible support PROFLY™ midsole for a unique balance of PROpulsion and PROtection Wishbone design and siping provides traction and strategic flex points Rubberized foam outsole for a lightweight, soft ground contact and responsive cushioning RN 88276
