Adidas Metalbone Carbon 3.4 2025

Technologies

Pros

• ✓Octagonal Structure cuts down frame torsion on off-centre hits, so your bandeja-3 smash still holds its line even if you catch the ball half a centimetre above the sweet spot The head-heavy balance combined with Power Extra Grip loads the handle with extra inertia: flat smashes and viboras come off the strings at a speed few diamond-shaped rackets can match The Soft Performance EVA core cushions impact and delivers a surprisingly soft ball exit for such a stiff, rigid profile — you feel it most on cut bandejas and blocked volleys The sandy, textured surface reinforced by the Spin Blade Decal really grips the ball: kick serves and short slice shots pick up genuine rotation, not just the feeling of it

Cons

• ✗At 360-375 g with weight up top, quick volley exchanges at the net take a toll — lose the tempo battle and repositioning the face for the second shot gets tough The sweet spot is compact and sits high on the face; low, forced wall exits come back feeling harsh and offer little help The 38 mm frame in a diamond shape leaves little margin on defence — a deep lob demands real arm technique, the racket alone won't bail you out It calls for early preparation and a well-developed wrist; an intermediate player still building their game will struggle with the weight and timing demands before ever tapping into the power

Pure diamond shape, a 38 mm frame and head-heavy balance: the Adidas Metalbone Carbon 3.4 2025 doesn't hide what it's built for. A 6K carbon face, Soft Performance EVA core and 360-375 g loaded toward the head, all on a 485 cm² hitting surface with a total length of 45.5 cm.

This is a padel racket engineered around one idea: let a player who already knows how to smash hit even harder without losing the line of the shot.

Who should actually be playing with the Adidas Metalbone Carbon 3.4?

This one's built for advanced players with an aggressive, attacking game. The diamond shape, head-heavy balance and 38 mm profile pile the mass into the upper part of the face: the ball comes off with serious pace, but the racket demands early preparation, a trained arm and timing that's already locked in on court.

Octagonal Structure: the frame that refuses to twist under pressure

The tubular octagonal carbon structure is the single biggest factor behind how this racket feels. Its job is cutting frame torsion on off-centre hits — that tiny twist that, on a conventional diamond, turns a well-struck smash down the line into a ball sailing long over the glass.

With less torsion, the face arrives more stable at contact and direction holds up even when you catch the ball above the geometric centre. That's the reason a racket loaded this heavily up top still keeps a reasonable amount of control on attack — a combination that rarely lives in the same frame.

Low Poly backs up that philosophy from the lower part of the frame: it trims and lightens the area near the throat so the weight lives where it should — up top — without bulking out the racket or pushing total weight past the 360-375 g range.

Soft Performance EVA and 6K carbon: stiffness with the handbrake on

The 6K carbon face brings stiffness and instant pop, with a response that's lively rather than harsh. It's not chasing the extreme hardness of ultra-high-density carbon, but a sweet point where the fibre pushes back without hammering your elbow on every ball.

The Soft Performance EVA core is the counterweight. A soft, premium rubber that stretches out that split-second of contact and hands back some feel to the shot, which translates into a generous ball exit on bandejas and blocked volleys.

That combination sums up the character of this Adidas racket: it hits like a power racket, but tells you where the ball is better than most rigid diamonds do.

Smart Holes Curve, Spin Blade Decal and the spin game

The Smart Holes Curve lays out the face's perforation in a curved pattern instead of a uniform grid. The practical effect is a different distribution of stiffness between the upper and lower parts of the face, which keeps the hitting zone from feeling like a plank of wood.

On the surface, the sandy texture combined with the Spin Blade Decal bites into the ball for real. Kick serves jump up off the bounce, and short slices at the net die on landing when you play them with an open face.

Power Extra Grip rounds off the package: the extended grip adds inertia to the handle and gives you extra leverage on the smash. It also lets you choke up a couple of centimetres when you need to defend and that top-loaded weight starts working against you.

The numbers behind the Metalbone Carbon 3.4 2025

Shot by shot: where it wins and where it costs you

• **Flat smash and bandeja-3**: this is its home turf. The top-loaded mass and stable frame turn a clean hit into a shot that breaks the rally's rhythm.
• **Vibora**: excellent. The sandy texture grabs the ball and the 38 mm profile supports the wrist through the sideways cut.
• **Bandeja**: better than expected thanks to the soft core, though it needs the shoulder driving the shot, not just the hand.
• **Volley**: solid and penetrating on the block, but demanding in fast exchanges where you need to flip the face twice in quick succession.
• **Wall exits and defence**: this is the weak point. A low, forced ball comes back feeling harsh if you're not hitting dead centre on the face.

Does this racket forgive mistimed shots?

Barely. The sweet spot is compact and sits high on the face, consistent with how a diamond distributes its weight. Well-centred shots get rewarded generously; anything late or struck low and off-centre falls short and lacks depth.

That's not a manufacturing flaw — it's the logical consequence of stacking mass up top on a 38 mm frame. Anyone after a racket that bails out their mistakes should be looking at round shapes with a lower balance instead.

Who it suits and who to pair it with

It suits the backhand-side player who steps in to smash and close out points in the air, or the forehand player who attacks through the middle and needs ball speed above all else. It demands physical staying power — that top-loaded weight makes itself felt in the third set.

As a doubles pairing, it works best alongside someone with a more manageable, defensive-minded racket who can hold the rally together while this one hunts down the winning smash.

Verdict: power from a frame that holds its ground

The Adidas Metalbone Carbon 3.4 2025 delivers exactly what you'd expect from a diamond shape and adds something many rackets in this category lack: stability on off-centre hits thanks to the octagonal build, and a controlled touch thanks to the Soft Performance EVA.

In return, it demands genuinely advanced-level ability, doesn't handle forced defence well, and punishes shots struck outside the sweet spot. If your game lives at the net and your usual miss is a smash going long, this racket gives you pace without losing control of direction. If your matches are won defending from the back of the court, this isn't the tool for the job.
