Remember having these as a kid? And how you always wanted the ones that came with glitter in the plastic? They bring back so many childhood memories of summer. But these clear jelly shoes are probably also the most adaptive footwear that exists, that go with every outfit and every color as it almost looks like you are bare footed.
Update: I got mine at the Albert Cuyp market in Amsterdam. But online you can find a pair of similar ones here.
