In 1930s Paris, tennis was often played in espadrilles. Unsatisfied with these unsuitable shoes, Georges Grimmeisen invented the G2. His creation combined:
- Breathable cotton canvas for lightness and ventilation.
- A vulcanized rubber sole capable of absorbing shocks.
- Four ventilation holes and a reinforced toe cap for durability and protection.
Quickly embraced by athletes like Björn Borg, Rod Laver, and Françoise Dürr, the G2 also won fans with its clean, refined design, foreshadowing its place in fashion.
