Have you ever had your legs measured by a physical therapist or equivalent? I used to do the same thing. The problem is that resting on one leg tends to push the hips out of alignment (it's easy to see in the mirror; the hipbones won't make a line parallel to the ground). For me, I would always get pain/numbness in my lower back on the side of my taller leg. Putting a lift in the other shoe and being mindful to keep straight helped to fix it. I had to be mindful (at least at first) because my body was so used to slouching sideways that it would still try to default in one way or another. I think that it's gotten better as the muscles re-learn the necessary patterns to keep straight. EDIT: BTW, I don't use a standing desk- I prefer to walk around a lot. Before my PT visit, I would get pain within 15 minutes of standing!
