Glover’s Shoeless Moment at 3M Open Sparks Spirited Explanation About Spike Marks

Lucas Glover, a former U.S. Open champion, removed his shoes mid-round at the 3M Open in Minnesota on Sunday, creating a puzzling moment that drew immediate speculation. The unusual decision came after Glover sank a 10-foot birdie putt on the 10th hole during the final round, when he slipped off his footwear before retrieving his ball from the cup.

Many observers, including Golf Channel analysts, initially believed Glover was making a silent protest against the AimPoint green-reading system, which he has publicly criticized. However, the PGA Tour clarified that Glover had been instructed to be mindful of spike marks on the putting surface, particularly given his metal spikes.

Glover finished tied for 57th at the event but took to Instagram with an extensive statement defending his actions and addressing the mounting speculation. He emphasized that his 23-year history on the PGA Tour wearing metal spikes had never previously prompted complaints until Sunday, when an official approached him during the round.

The golfer stressed that removing his shoes was simply the most effective way to avoid leaving additional marks around the hole, regardless of spike type. He repeatedly noted in his statement that players are permitted to tap down spike marks during play and that bent grass greens at 3M, softened by watering and weather concerns, would show wear from any footwear.

Glover concluded his detailed response by clarifying that his demonstration had nothing to do with AimPoint technology and lamented that media attention focused on what he deemed a non-issue rather than fellow golfer Jackson Koivun. He announced his intention to compete at The Rocket Classic while continuing to wear metal spikes.
