Abstract
Described herein are embodiments of golf club heads with slits and flexure inserts. The slit comprises an opening through the club head body communicating between the exterior of the club head and the hollow interior cavity. The flexure insert can comprise a spring component and a cap. The spring component creates a spring effect within the flexure insert that increases the internal energy of the club head at impact, leading to improvements in ball speed and other golf ball performance characteristics.
