Socks as slippers

Short answer: A thick sock with a non slip sole is warmer than a slipper and takes up no space. Without a sole you slide on a smooth floor.

Why socks beat slippers

A sock lies close to the foot and therefore holds the warmth better than a loose slipper with air around it. It is also easier to wash and takes up no room when not in use.

The sole is necessary

On parquet, tiles and laminate an ordinary sock is slippery. Choose a style with grips or an applied rubber sole. See bamboo socks for women.

The material

Bamboo viscose keeps the foot dry, which matters more for warmth than thickness does. A damp foot gets cold however thick the sock is. See bamboo socks for men and bamboo trainer liners for women.
