Girls, do your socks slide down in your shoes? How do you avoid that?

I'm tired of replacing my socks so I don't care anymore and let my socks sliding down.
Now I'm so used to have my heels uncoverded into my sneakers that I don't feel the difference when they slide off. I don't even replace them when I remove my shoes and my heels stay exposed.

But after a while, the back of my foot starts bleeding.
Do you have any solution?
