I'm told that the high end saunas in Macau, patronized by rich Chinese, are 'staffed' in part by statuesque Russians and Poles.
I'm also told, Silverboy would be able to confirm this, that Thai women and men are particularly sensitive to the 'fragrance' of foreigners, Indians, Arabs AND Caucasians. Perhaps female Thai feet are less 'potent' than our own.

You have of course left out a race- don't blame you mind, otherwise I wouldn't be reading your post now. But actually those don't particularly whiff from the feet. As far as the feet are concerned SB was right you don't need socks in Thailand. Actually though socks and sandals are okay. Don't forget, cotton cotton cotton or wool wool wool. I;m sure you is a fragrant person, Trumpsey?
