Feet are pointing out too much and the movement is coming from your ankle judging by how your knees track. So ankle inversion/eversion limitations also show up in the heel lifting up. Oly lifting shoes do ankle dorsiflexion not so much inversion/eversion… actually I think they might limit those movements lel. Also flat fleet or collapsing arches would cause a similar heel lifting off.
Feet pointing out is meant to be from external rotation at the hip not from movement at the ankle joint. This means your knees should track in line with your toes. Might be the camera angle but this looks like a problem for you. Widening your stance or pointing your toes in at the ankle won’t help the issue.
A sequence I learnt a while back to find a good foot/knee/hip position:
Pick one foot slightly off the ground and flex your glutes and quad as hard as you can.
This will make your hip do some combination of externally rotating (rotating your whole leg and thus pointing your feet out) and abducting/moving your leg and feet away from midline i.e. stance width.
Repeat with the other foot and you have your stance. Tweak it a bit to taste but remember it’s all in the hips.
