Standing desks work best when used with a treadmill specifically designed for and optimized for walking. Standing for long periods, especially on hard flat floors, will also cause problems (an anti-fatigue pad beneath your feet will help with that). Being able to stand and move with a steady slow pace imparts the greatest benefit and avoids the problems of standing. And even with a treadmill, there are tasks you'll do better sitting. Alternating sitting and standing, and often walking while standing, feels great. Our ancestors evolved to walk and run long distances with varied movements to gather food and hunt, not to stand in one place for hours looking straight ahead or straight down.
