The world will be watching as American sprinter Tyson Gay takes the track for the 100 meters on Sunday August 5th. Tyson will be competing against the likes of Usain Bolt in this pair of adizero Prime SP spikes. It will be hard to miss the American flag upper design and Tyson’s speed. As Adidas’ “lightest sprint spike ever”, the Prime SP weighs 3.5 ounces, making it 62% lighter than the adizero Demolisher which was worn at the 2008 Beijing Games. Look for the adizeor Prime SP at your local track this year as the sprint spike will be available to the public for $212 this month.
