Vise Silicone Semi P/O Grip Insert Blue

The release is the shot. A seated insert makes it repeatable.

Silicone grips the skin without trapping the finger. That balance is what bowlers with clean rev rates protect.

Performance Under Pressure: The semi P/O cut loads the fingertip on the way down and releases clean on the way up. One insert, two reactions on demand.
Durability: Silicone holds shape after dozens of tape changes. The insert outlasts the bowler's practice cycle.
Friction Removal: Sized to fit the drilled hole tight. The finger stays locked through the swing, not sliding mid-release.
Identity Signal: Blue reads bright against any cover and tracks easy on lane video.
Proof and Credibility: Pro shops reach for silicone when the bowler wants a forgiving feel under a firmer tape stack.

Revs live in the fingertip. Build the grip like a pro.
