We use Collégien slippers since KleinR {not so small anymore actually} was around 1 1/2 years old.

They are comfortable and soft, do not slip because of the little spikes on the sole, have a perforated breathable sole and come in really cool designs.
Basically everything you can imagine – funky, classic, stripes, faces, long versions as well as short, cashmere for extra luxury and and and… have a look, I am sure you will find something you like.

And they do them in adult sizes too… are you ready for the family look?
