Flip-flops scrub between toes
Who does not know that? It's way too hot, the idea of closed shoes makes you sweat.
The only thing that helps are flip-flops, but after a while, between their toes, they start to rub. Ouch!
What good against it helps:
Tear off a small strip of cling film, crumple it a bit and then wrap it around the bridge of the flip-flops. The foil keeps wrapped by itself.
After that, nothing scrubs anymore!
