Flip-flops are the simplest and lightest type of sandal: a flat sole held to the foot by a single Y-shaped strap that passes between the big and second toe. The name 'flip-flop' in English is onomatopoeic — from the characteristic slapping of the sole while walking. It is minimal footwear, made for the beach, the pool, the country house and hot climates, where the main things are lightness, speed of putting them on and the fact that you do not mind getting them wet. Flip-flops cost next to nothing, weigh almost nothing and fold into any bag. Classic rubber models are an attribute of every summer holiday, though there are also more expensive leather and designer versions. They are the embodiment of carefree summer and beach relaxation: simple, practical footwear in which comfort and unpretentiousness matter more than any formality.
