Un Rio Knit is part of the Unstructured family of Clarks shoes, meaning they are light, cushioned, and very comfortable (making them a great travel shoe). The uppers are made of and lined with a breathable knit fabric, white subtle leather accents and an elastic over the top of the foot. The sole is EVA which will help make them light, and combined with the dual density cushion insole, very cushioned as well. The modern silhouette means they can even be dressed up a little bit.
