Josh Kerr’s mile world record was not only a story of fitness and race execution, but also of equipment built for a very specific goal. According to Runner’s World, the Scottish middle-distance runner worked with Brooks on a custom spike created to support his attempt at the iconic mark.
The concept behind the shoe was unusually direct: make Kerr feel as if he were running downhill. That design idea was meant to turn the spike into a competitive advantage, helping deliver the aggressive, fast-moving sensation needed for a record attempt over the mile.
The report suggests Kerr’s push for the record was a collaborative project rather than a solo mission. After setting his sights on the long-standing standard earlier this year, he leaned on shoe specialists to tailor a model around his racing needs, with performance gains targeted at one of track and field’s most famous distances.
Kerr’s success highlights how elite middle-distance racing now blends athlete preparation with highly focused product development. In this case, the custom Brooks spike was designed not just as footwear, but as a purpose-built tool for one of the sport’s biggest achievements.
