Potterlassie is right; can be very common w/rheumatology&autoimmune issues. The bottoms of my feet turn bright red and "puff" up a bit when i'm having a flare. Took me a while to figure it out. My PT was shocked on day, he said he had only seen feet that red with marathon runners!
Also, recently was in Hawaii and my feet swelled up...looked like little pineapples. Sometime pressurization (ie airplanes) can do that too.
