If you already swing a Project Boomstik®, the Boomstik® ST™ keeps the power players love and adds spin longevity, additional control, and a weight setup you can tune yourself.
Since its release, one word has been impossible to ignore in pickleball: Boomstik. Selkirk's 2025 Labs Project Boomstik® added 12% more exit velocity than a comparable Gen 3 paddle and quickly became a tournament favorite.
The Boomstik ST is the next evolution. Same explosive core. New grit, a new face design, and adjustable weighting. Here's exactly what changed, what didn't, and who should upgrade.

Durability: Built to last longer
The original Boomstik's core was already built for the long haul. The ST's durability gains come from the surface and the weighting.
The core stays bulletproof. Both paddles use a PureFoam core surrounded by an EVA Power Ring. That means no core crush and no break-in period. The Multistrata face, a patent-pending multi-layer T700 carbon-fiber system, also carries over for consistent energy return and rock-solid durability.
The grit lasts twice as long. On most paddles, the surface is often the first thing to go. Once the texture smooths out, so does your spin. InfiniGrit® Ultra has 50x the texture hardness of the original InfiniGrit, giving it double the durability for longer-lasting grit.
The weights hold steady. The original used semi-permanent perimeter weights clamped to the edge guard. The ST's Adjustable MOI weights are designed to stay locked in place and will not shift during play, even after you adjust them. Whether players are using the weights in power, control, or not at all, the paddle remains solid.
InfiniGrit Ultra: Extreme spin that doesn't fade
Boomstik ST is the first paddle with Selkirk's new USAP-approved InfiniGrit® Ultra, and it's the biggest single upgrade over the original.
Compared to the original InfiniGrit® on Project Boomstik, InfiniGrit Ultra delivers:
- 4x more friction for spin creation
- 50x the texture hardness for long-lasting grit
- 2x the texture durability game after game
What that means on court: heavier topspin drives, sharper slices, and dinks that dip harder. And because the texture stays put, the spin you get in your first session holds up far longer. You'll have more chances to shape your shots, match after match.
Control upgrades: Sharktooth™ and Adjustable MOI
The original Boomstik was all about ending rallies. The ST adds the tools to win the points that don't end on a drive.
Sharktooth™ Groove Technology: More dwell, better resets
The "ST" stands for Sharktooth™ Technology. It's a perimeter groove around the paddle face, cut to a precise profile shaped like a great white shark tooth. You can see it at the edge of the face, near the paddle handle.
The groove acts as a hinge point. It flexes so the face can bite the ball, which adds dwell time and retains spin and speed across the entire face.
On court, that means: more predictable resets from the transition zone, more aggressive dips over the net, better spin, feel, and consistency, even on off-center hits.
Adjustable MOI Tuning System: tune it to your game
First introduced on the Selkirk OMNI™, the Adjustable MOI Tuning System weights the paddle for maximum sweet spot and balance right out of the box. Unlike the original Boomstik's semi-permanent weights, you can remove and reattach the ST's perimeter weights by hand to customize performance to your style. Once set, the weights won't shift during play.
What stays the same: The signature Boomstik power
If you're worried the upgrades soften the hit, they don't. The ST keeps the same explosive power from the original Project Boomstik, still rated 10/10 for power.
- Same PureFoam™ BoomCore™ with EVA Power Ring, 16 mm thick
- Same Multistrata T700 carbon face for optimized flex and energy return
- Same two shapes: Widebody (forgiving sweet spot for extra control) and Elongated (more reach and plow-through)
- Same grip: 4.25" circumference; 5.6" length on Widebody, 5.8" on Elongated
Should you upgrade?
The ST is built for intermediate-to-advanced players who want maximum power without giving up consistency or durability. Here's how to decide.
