The flip flop
The tong, tongo or barefoot, also called gougoune in Quebec or simply sandal, slache in French-speaking Belgium but more particularly in Brussels, or savate (savate two fingers) or clapper in the France of overseas
The origin of the tong is Egyptian around 5500 BC. At first, they consist of a simple rigid papyrus sole woven with leather straps.
The tong migrates to China and Japan where it becomes "zōri" then "geta" in the twentieth century.
It was the Japanese zōri that inspired the Brazilian company São Paulo Alpargatas when it created the Brazilian flip flop, the Havaianas.
Its use then spread widely to the entire planet
It is in Brazil, where we find the world's largest producer, Alpargatas, which in 2012 sold more than four billion pairs of Havaianas worldwide.
