I recently did a week long stint on a temporary standing desk before ordering new longer legs for my current desk. For the first few days my feet hurt after standing for an hour or so, however I did find that I felt more energetic throughout the day. I did have an odd feeling of being unsettled the first day, but after that I found it easier to focus, especially with the extra energy. By the fifth day the pain in my feet was significantly reduced. This week I've returned to my (fairly) ergonomic sitting desk setup and I've noticed posture issues and some discomfort in my lower back. My experience was that alternating short periods on a tall stool with standing provided the most comfort. The paper, "The benefits of sitting and standing to work" (http://www.ergomotion.com.au/images/PDF/HFESA%20paper%202008%20%20illustrated.pdf http://www.ergomotion.com.au/images/PDF/HFESA%20paper%202008...), references a study in which 30 full-time bank tellers came to the same conclusion. Using a chef's mat can also provide some comfort for your feet.
