The standard wader boots for fly fishing are so very expensive that these are a great, reasonably priced, and high quality substitute. I normally wear a 13D, so I ordered a 14 for the purpose of wearing these over my stocking foot waders. These are just great for this purpose. They maintain a good grip even in swift water and on slick rocks, and they even match my waders pretty well.
The grommets allow water to drain, and the canvas fabric dries out quickly. Even the shoe laces are pretty good quality. Just be sure to order a size or two larger than your normal boot size if you plan to wear them over stocking foot waders.
Tight lines to you.
