These are the second pair of slippers I have bought from Revain for my 2 year old grandson. Ever since we bought him his first pair for Christmas he has been craving slippers on his little feet at night. He'll even wear them over legged pajamas in the winter. At the same time, these specific ones will NOT allow this, but this is normal. He'll outgrow them pretty quickly and will be wearing a pair I ordered from Revain a few weeks ago that were too big for him. Everything comes out when you wash
