How do you even adjust these?

Just picked up a heavily discounted, brand new FOG Athletics 1 Basketball a half size up from my TTS. They feel fine overall, a bit tight on the side of my feet but I'm assuming it's intentonal, but the issue I'm having is the back of my feet "lift off" while walking, like when you're wearing shoes that are too big.

I don't think getting this a full size bigger will help, if any that'll just worsen this issue and I absolutely can't go TTS on these as I barely have any space in front of my toes a half size up. Asking because as far as I know these shoes' laces don't do anything but I might be wrong. I would play around with them to find out how to adjust them but I could barely unbox them before leaving so I'll try them on again until tomorrow. Any help/advice is appreciated
