Under Armour has been testing out a smart golf shoe, and the prototype was worn by Jordan Spieth at last weekend's The Open golf championship.

A fully paid-up Under Armour ambassador, Spieth was wearing a golf version of the Speedform Gemini 2 Record Equipped smart running shoe that was released earlier this year.

Those shoes are fitted with an accelerometer that estimates steps, distance, speed and calories burned. While in the SpeedForm this was designed for running, for golf this is tweaked for walking the course, which can be in excess of 10km to walk around.

Under Armour also published the results of Spieth's round, which are entirely what you'd expect from someone who played a round of golf, but demonstrates the kind of data smart shoes can capture. The shoes recorded 13,541 steps and 1,984 calories burned on the final round.

Apparently, Spieth is a bit of a geek for his Under Armour Band during workouts (it's amazing what a multi-million dollar sponsorship can do) but he can't wear his tracker on the course.

The company hasn't offered up any details on when we might see Under Armour connected golf shoe hitting the stores – UA only released its dumb golf shoes in April 2016. But it seems Under Armour is driving on with its sports tech ambitions.
