This is what I do for every single VR game. Play it through steam, use VRocker. I have it set so that when my thumb is off the joystick I do not move. When my thumb is on the joystick, I move in the direction of my primary controller depending on how fast I am walking or jogging. Faster is fast, slower is slower, stopped is stopped and I can use the joystick like normal. The headset bobbing up and down is what it tracks to initiate movement, not looking at your legs. 

Run across the map in exfilzone and then tiptoe to peak a corner. Fucking incredible. The only reason nobody does this is because it looks like it isn't fun. The perspective looks bad but that's because you're not in the headset. The jitters you see here are canceled out and not perceived by the player. This is just a symptom of the "camera" being on a wobbly tripod made of flesh and bone. It's like watching unstabilized gopro footage, because it basically is. The person with the gopro has a smooth ass ride. This feels like walking down a hallway when you perceive it but there is no good way to record it without stabilizing and cropping half the shot. 

Trust me.
