I was looking in the dictionary for the name of usual indoor shoes which are used by kids in the house. I found 'slippers'. The explanation of the term is in relation to the attributes. Therefore it seems inappropriate to describe flip-flops as slippers. Flip-flops are pretty common in Germany in the house during summer.
Is there a name which includes all different kind of shoes, which are worn in the house?
What are some examples for pretty common shoes used inside the house during summer or winter?
