All golfers, even the best Tour players in the world, miss the center of the face from time to time. And when you lose speed relative to a center hit, the ball doesn't roll as far as you intended, so you miss more putts or leave them farther from the hole. Now in Odyssey Ai-ONE, they've leveraged Callaway's industry-leading Artificial Intelligence design and super-computing capabilities to create the most advanced insert in golf. 

The multi-material construction includes unique contours on the back of the face that minimize ball speed losses on off-center hits, and greatly increase the sweet spot. Odyssey's revolutionary Ai-ONE urethan insert delivers more consistent ball speeds, even from off center-hits, leaving puts up to 21% closer to the hole.
