In the 1930s, tennis gained widespread popularity. An amateur tennis player, Georges decided to create a pair of ventilated shoes, made of cotton canvas and vulcanised rubber, perfectly suited to clay courts. Rather like springs, the G2 can be summed up in three words: flexibility, seal and adhesion. Very soon, tennis players began preferring Spring Courts to espadrilles. They became one of the first examples of shoes created for high-level sport. Lew Hoad, Jan Kodes, Bjorn Borg, Ilie Nastase, Rod Laver, Françoise Dürr, François Jauffret, Pierre Barthès... The list of players who adopted them grew ever longer.
