I have been wearing Crocks for wet riding. I wore a pair today in fact. I used the Crocs Swiftwater leather model today. In the Summer they are great. If they get wet, they are dry in a very short time. I wear them without socks on the Summer so your feet don't get soggy. Today though it was cooler. I wore a pair of wool socks. The Crocs actually kept the socks mostly dry today, and wool stays warm even when wet, so I felt fine all day. They stick very nicely to a a pair of pedals like the Wellgos.
Today was the first colder day I tried the Crocs. I was quite pleased with them, although I have used waterproof hiking boots in the past once the weather got cooler. I have gone as far as using hunting boots from Rocky Boots once Winter hits. They are Goretex and insulated with Thinsulate. They worked great once the snow began. For now, into the 50s, the Crocs Swiftwaters with the wool socks will work for me.
