try thinner socks, thicker ones might be helping your already small boots cut off circulation.
make sure your liners and boots are pre heated, I put mine in the passenger side by the foot heater vent in my car and blast it uncomfortably hot for the last 10 minutes of my drive
Also one thing I do is not wear my ski socks on the way to the mountain because your feet will sweat (even if you don’t notice it) and get your socks damp before you even get on the hill, I pull off my regular socks and let my feet air dry before I put on fresh ski socks every time now and it’s helped a lot.
if all that doesn’t help you just gotta accept the boot glove and a heated insole/sock
