I see from the archives that there has been some discussion in the past about the similarity between Kilt Hose and Shooting Socks. Here are a couple of sites offering Shooting Socks (your friends at Google can show you more).

They seem to be less expensive, and less conservative in colour and style (not that that's necessarily a bad thing) than the sources for Kilt Hose.
