I got an adjustable standing desk a couple of months ago. It took a little bit of getting used to, but less than I expected. At first the sit/stand ratio was around 50%, alternating every couple of hours. Now I just tend to sit if I am eating lunch or really tired. A side benefit (as someone fairly tall) is that the sitting height is about 2 inches higher than my old desk which is more comfortable too. There was no foot pain, and I don't use a mat to stand on, but I do tend to move around a fair bit. My back pain is gone too and I've got less trouble than I've had with it in years. My general 'altertness' level has also gone up. I'm not in great shape either (20 years in IT) though I've been starting to run more this year which has helped as well.
