When building sand castles gets a little old, send your tots off in a pair of kiko+ by Kukkia sandals. From the top they may look like any other pair of beach shoes, but flip them over for a surprise.
Each pair comes with a reverse-cookie-cutter animal footprint, so kids can tromp around and leave behind a series of slightly unusual pawprints.
Unfortunately, these sandals only come in children's sizes.
The options include cat, monkey, owl, gecko, and even dinosaur tracks.
These sandals are made out of wood, so it's safe to say they won't get much wear outside of the beach, but it's still a fun option to toss into the beach bag for future beach trips.
