The eight-time Olympic gold medalist sported this specific pair during the 100 meter heats at the London 2012 Games, as reported by BBC News. Dressed in white, blue and red, the spikes were 'part of an extensive collection [the collector] built-up over the last 10 years'. Only four or five pairs were signed during the 2012 Games.
While a 35-year-old man has been arrested in connection with the theft, the actual shoes are still missing. Anyone with information regarding the shoes whereabouts are asked to contact Derbyshire Police.
