I'm a retard with too much money who bought a valve index recently and now want to try out full body tracking. 

I'll need three vive trackers ($300), a way to attach them (trackstrap, $100), then I hear they have battery problems so will need 3 powerbanks ($90). So $490 + shipping/tax total? 

How the fuck do you even attach shit to your feet, you'd be constantly stepping on the straps every time you take a step, they would get fucked up pretty quick and also mess up your balance? Barefoot? Socks? Shoes? At least the waist should be easy, right. 

You don't need a hub as long as you have enough USB ports right?
