In March, Jordan Spieth launched Under Armour's first line of golf shoes.
At the U.S. Open last month, Spieth and Under Armour tried something a little different -- a "smart' shoe with sensor technology.
"When it comes to daily activity, Jordan could not wear a wearable device (UA Band) on the course to track his performance during competition," said a release on the technology.
So Under Armour created a shoe for him incorporating the same devices found in the brand's "smart" running shoe called the Speedform Gemini 2 Record Equipped.
"Data was collected through an embedded motion sensor within the midsole of the shoe that automatically tracked performance metrics such as distance and steps – a total of 13,541 steps for the complete 18-hole course," the release said.
Spieth, the 2015 U.S. Open champion, finished nine-over-par this year.
