Thanks for all the recommendations! I now have a list of boots to check out, but I ended up not being able to pass up these this past weekend at the Washington, DC Green Festival (tm). The boots usually sell for $65, and were on a show-only special for $45. I liked the look as well as any others I'd seen, and the price was great, especially when items like this with high recycled content often sell at a premium just because they're recycled/hemp/etc.

Thanks again to all.
