Ski jumper Janne Ahonen has won two individual World Championship titles and several more in team competitions. He has also taken two Olympic silver medals in the team event.
Ahonen’s smartwear shoes are equipped with a measuring system that gives feedback to the athlete and the coach after each jump. Sensors in the shoe collect data on movements and pressures of the foot. After each jump the data is used in analysing the speed, timing and flight trajectory of the jump.
Janne Ahonen used these shoes in the 2007–2008 season, when he won his fifth Four Hills Tournament title. Analysis of data provided by the shoes showed that Ahonen was able to repeat his performances much more consistently than any other ski jumper.
