Puma El Roo (Preschool)The Puma El Roo is undoubtedly one fashionable shoe. Adopting the simple and iconic rubber band from the popular Puma El Rey slip-on, the El Roo combines that element and the silhouette from the wallaby. It features a rarely seen corduroy upper and a faux fur lining that is sure to keep your feet warm and comfortable. The El Roo is currently available in both mid and low models.
