The Crocs Pollex Clog Salehe Bembury Stratus has a striking exo-skeletal appearance with concave ridges throughout its foam structure that resemble fingerprints. Compared to classic Crocs Clogs, this design has fewer ventilation holes, but the ones that are there are situated on hot spots on the foot to improve breathability. A canvas strap that can be removed at the ankle gives wearers an option for a more snug fit.
