3-D printed shoes that could help sprinters shatter records  JUL 12 2012

For his final project at the Royal College of Art in London, Luc Fusaro outlined a process for building custom-fitting sprinting shoes that weigh just 96 grams.

Laser Sintered Shoes

The shoes are fabricated using a selective laser sintering process that uses precise 3-D scans of an athlete's foot to achieve maximum fit. The really tantalizing (but unfortunately uncited) bit about Fusaro's design is that by fitting shoes to a sprinter's feet so precisely, significant performance improvements might result:

Scientific investigations have shown that tuning the mechanical properties of a sprint shoe to the physical abilities of an athlete can improve performance by up to 3.5%.

For 100-meter world record holder Usain Bolt, a performance improvement of 3.5% could lower his world record to 9.24...just by wearing different shoes. That seems insane but Speedo's LZR Racer suit that was responsible for dozens of world records falling in 2008 were shown to lower racing times by 1.9 to 2.2 percent so that sort of improvement is certainly possible.
