Put your foot trackers on your feet, not your ankles, so that you get foot rotation too. Strap them there using either trackstraps or tundra straps or some cheap knockoff solution or use tiewraps or shoelaces to keep them on some shoes.

Put your hip tracker ideally on your front or back of your hips, whichever will get in the way less. Usually that's the front since people sit down often. You can put it on the sides of the hips but you'll get tilted hips in some positions. Again use either tundra or trackstrap or you can use an old belt and tiewrap it to it.
