Slippers/slipper socks that will stay on cruising 12mo feet

Recommendations? Our floor is freezing already

My dd is only 8mo but she's wearing socks from Sainsbury's that have little rubber knobbles on the soles. They pull up like knee socks and then we put leggings/ jeggings on her and the socks stay in place.

Moccasins from places like dotty fish are soft enough to wear indoors. And my sock puller 14mo isn’t able to take them off.
