The selfies of dangling feet, immersed in the waters of the sea or of a swimming pool, on the beach or swinging from a deckchair or a sunbed, multiply exponentially on our social walls with rising temperatures and the arrival of summer.

Or, more trivially, is it just a passing trend? Posterity will judge!
