I bought a pair of these type of socks for our Austria trip; while I can't remember which brand they are, they are skinny enough to fit in my road shoes. They definitely kept my feet dry on the one very rainy morning. However, my feet were sweating like crazy. I have worn them mountain biking and hiking where I knew there might be stream crossing issues, but only in the spring or fall. They would be hot in the summer. Still, I'm glad I have them as a back up.
