Siux Electra ST4 Pro 2025 — Review
The Electra ST4 Pro 2025 is the next step in the Stupa Electra line: a competition-ready hybrid with a medium-hard feel and strong performance at high pace. 15K carbon + Hard EVA deliver a connected, stable impact and controlled power for players who want to dictate rallies without sacrificing accuracy.
Verdict
If you want a true all-round racket with an attacking edge, the Electra ST4 Pro 2025 is a strong pick. It’s fast for a hybrid, stable at the net, and has that medium-hard “connected” touch that rewards clean technique. It’s not the softest or most forgiving option, but in skilled hands it delivers pressure, consistency and finishing ability.

Pros & Cons
Pros
- Excellent power/control balance for competitive play.
- Connected medium-hard feel that rewards clean technique.
- Strong net stability on volleys and fast blocks.
- Great spin bite thanks to rough finish + 15K carbon.
Cons
- Only medium comfort (not ideal for very sensitive elbows).
- Less forgiving outside the sweet spot than soft rackets.
- Needs technique to shine from the back of the court.
On-Court Performance
Back of the court
From the back, the ST4 Pro rewards early preparation and clean contact. When you hit well, it delivers depth and direction with confidence. It’s not a trampoline-soft racket, but the response is predictable and very “readable” under pressure.
At the net
This is where it wins you over fast: stable blocks, firm volleys, and a point-and-shoot feeling into lines and feet. The medium-hard touch helps keep the ball low and heavy without needing huge swing speed.
Overheads (bandeja, víbora, smash)
The bandeja comes out deep and controlled. The víbora is sharp and spinny with a naturally uncomfortable trajectory for opponents. Smashes have serious finishing power when you have time and technique, without being as extreme as very head-heavy diamonds.
Comfort & vibrations
Feedback is solid and connected. Vibration filtering is decent for a pro-oriented frame, but it remains a medium-hard racket. If you’re coming from softer rackets, you’ll feel the difference in the first sessions.
Who it’s for / not for
Great choice if…
- You’re an upper-intermediate/advanced player wanting an aggressive all-round hybrid.
- You like a firm, quick response on volleys and víboras.
- You play pressure padel: net, transitions and finishing.
Avoid if…
- You’re a beginner or need lots of free ball output.
- Top priority is maximum arm comfort.
- You prefer a very soft touch and a huge sweet spot.
