Spinwave Certified Pre-Owned
Condition: Mint — limited quantity available
Certified Pre-Owned stock is limited and does not restock. Photos on this listing are representative of the condition you'll receive.
At the heart of the Boomstik is BoomCore™ — a PureFoam™ core encased in an EVA Power Ring, engineered for explosive, long-lasting pop. Paired with a three-layer Multistrata T700 carbon face and the InfiniGrit™ surface, it's a pure power paddle that keeps its bite far longer than standard raw carbon.

Who It's For
Players who want a pure power paddle with reach — built to dominate from the baseline to the net. The 118 swing weight gives real plow-through on drives, so it rewards players who generate their own swing speed. The MOI weights let you dial it back if you want quicker hands. If you're coming from a control-first paddle and want to add put-away power, this is the jump.
