The Selkirk Boomstik is Selkirk's power pickleball paddle, built around a 16 mm BoomCore and a perimeter MOI Tuning System that widens the sweet spot. There are two versions at Racquet Point: the new Boomstik ST, launched November 10, 2026, and the original LABS Project Boomstik, released in August 2025. Both come in Elongated and Widebody shapes, and both are rated 10 for power and 10 for spin by Selkirk.
Racquet Point is an authorized Selkirk dealer. Every Boomstik we sell is new and backed by Selkirk's Limited Lifetime Warranty. Compare the two below, or browse every Selkirk pickleball paddle we carry.
What does "ST" stand for on the Boomstik ST?
ST stands for Sharktooth Groove Technology. It is a groove that runs around the perimeter of the paddle face. Selkirk designed it so the face holds the ball a fraction longer on contact, which adds topspin, makes drives dip sooner over the net and helps resets land softly.
Sharktooth is one of three changes from the original. The other two are a harder, grippier face surface and weights you can move yourself.
What's new on the Selkirk Boomstik ST
InfiniGrit Ultra + Sharktooth
The ST is the first paddle with InfiniGrit Ultra, a USAP-approved surface with four times the friction of the original InfiniGrit and 50 times its texture hardness, so the bite lasts far longer. The Sharktooth groove adds dwell time on top.
Adjustable MOI Tuning
The perimeter weights come set for the largest sweet spot and an even balance. On the ST you can slide them by hand: lower for more stability on blocks, higher for a quicker head in hand battles. They hold in place during play.
The same Boomstik power
Underneath is the 16 mm PureFoam BoomCore fused to an EVA Power Ring, with a Multistrata face of layered T700 carbon fiber. It is built for exit speed with no core crush and no break-in period.

Selkirk Boomstik ST
For players who already hit with pace and want more spin and a surface that keeps its grip. The adjustable weights let you tune the paddle as your game changes.
Selkirk LABS Project Boomstik
The paddle that started it: the same BoomCore power and factory-tuned MOI weights for less money. The Canyon Clay and Calypso editions are the best value in the line.
Which Boomstik should you buy?
Elongated or Widebody?
Elongated (16.5 x 7.45 in). The longer face and 5.8 inch handle give more reach and more plow-through on drives, and leave room for two-handed backhands. The higher swing weight puts more mass behind the ball. Singles players and baseline hitters usually prefer it.
Widebody (15.95 x 8.0 in). The wider face has the higher twist weight and Selkirk's top sweet spot rating of 10, so off-center hits stay steadier. The lower swing weight makes it quicker at the kitchen line in fast hand battles. Doubles players who live at the net often pick it.
Both shapes weigh about the same and share the same core, surface and grip size, so the choice comes down to reach versus forgiveness.
Warranty
Both Boomstik paddles carry Selkirk's Limited Lifetime Warranty (U.S.) against manufacturer defects. Register your paddle with Selkirk to activate it. Warranties are handled directly by Selkirk, so claims go through Selkirk's warranty page.
