It’s festival time so that means it’s time to get yourself a pair of Havaianas (and probably some wellies, it is the UK after all). Black Havaianas are probably the best as it doesn’t matter if they get dirty. All Havaianas are waterproof and can be washed, but when you are camping out for 3 days you don’t want to have to bother cleaning your shoes. If you visit a festival that has showers you can wear them in the shower.
