I bought these because I love my other Zerogrands but they let water through the perforations when I get rained on. I do a lot of urban walking. These are fully lined, so with some sprayed on waterproofing I hope they will keep feet relatively dry. These are a darker blue, the color is brighter than I thought but is a very pretty color. They are stiffer than my unlined zerogrands but still very comfortable and flexible. They are light weight and well made but don't have the 'weightless' feeling of the unlined version. I have a medium wide foot and they fit a little large with a thin sock liner but not enough to want a smaller size. All in all, a very good shoe.
