I use it all day (maybe 8 hours a day), but I move around a lot. Whenever I'm not typing or reading on the screen (thinking), I walk around. That helps a lot. I sometimes go sit down a bit in other rooms, but basically I can stand all day if I have to.
It took my about 3 weeks to get to that point. For the first few weeks, my feet hurt a lot. But at some point I passed a threshold and it pretty much stopped hurting altogether as long as I can walk around and shift my weight from one leg to the other a lot (I couldn't stand still all day).
