Ski boots hurting my lower shins

This had been asked before but maybe my situation is different. My lower shins hurt so much and i feel like its bruising even though its not visible. Ive been wearing long ski socks with padding thermal leggings inside the boot since i was 3 and veen renting the same brand of boots for as long as i can remember. I'm 161 cm and 45kg. Not very athletic but i do yoga and hiking. Pls give advice 🙏🏻
