Some people get a special mat to stand on, say you really need it.

Should I try standing desk again I think I'll take your advice and get the special mat. Also, reducing my standing time would be an improvement
I have polished concrete floors in my apartment. Concrete is VERY hard and very fatiguing to stand on for long periods. I got a large cork mat (http://www.amazon.com/gp/product/B001QGYIDW/) to stand on which makes a big difference -- I think standing on something too spongy is just as bad as standing on something too hard. Many of the commercial standing mats looked too soft.
I'm also in very good physical shape (I routinely squat more than my body weight of 180), but there is an adjustment period when you go from sitting all day to standing. Taking frequent breaks is key -- every hour or two, sit or walk around for 10 or 20 minutes.
So if you feel fine with your level of exercise and sitting don't sweat it.
