Balenciaga’s Speed Trainer first debuted back in November 2016 and has since become the must-have sporty accessory of the moment, worn by a bevvy of style icons and A-listers.

The ‘S’ in Triple S stands for sole. In other words, this shoe has three of them. Molds were taken from a running shoe, a basketball shoe and track shoe, which were then stacked to create the 6.5cm platform that gives the Triple S both its unique look and its name.
