Are those the new version of the reebok power? I hate you - give me your shoes.
In all seriousness you should squat in a squat shoe, but those are amazing for deadlifts if you prefer flats.
Looks like you aren’t getting your knees out far enough. This causes some impingement at the hips and prevents you from getting to depth. So try shoving them out more and/or move your stance in a tiny bit.
Also, don’t look up. Stare at the floor 6 ft in front of you.
Additionally the bar seems to be floating over the spine of your scapula. You may have to inch it down a bit on your back during setup and lock it down with the lats during your set.
Finally, you have to bend over more and get your ass back further.
