Adidas Metalbone Youth 3.4

Technologies

Pros

• ✓Soft Performance EVA rubber does the work on groundstrokes: young players who haven't yet built up arm speed still get the ball clearing the net from the back of the court without forcing their swing The high balance in a 345-360g frame delivers head weight without real weight: the smash off the back wall and the bandeja arrive with enough momentum to avoid falling short at the net The Spin Blade 3D on the rough surface grips the ball nicely on viboras and cut drop shots, exactly where a young player starts to get a feel for spin Octagonal Structure and Structural Reinforcement keep the frame stable on off-centre hits, which any junior who isn't yet nailing the sweet spot every time will appreciate

Cons

• ✗The diamond shape stacks the sweet spot high up: on low wall exits and rushed defensive volleys the response turns harsh and forgives less than a round-shaped racket Fine control isn't its strong suit: in long rallies with cross-court balls to the feet, dialling in depth is tricky, since the soft rubber tends to send the ball long The high balance means preparing earlier on defence; if the young player is late to the ball, the head-heavy weight takes over and the block falls short At 345-360g it's still a lot of racket for an underdeveloped 8-year-old: players at the top of the age range get far more out of it

adidas Metalbone Youth 3.4: the diamond padel racket built for a 12-year-old's hand

The adidas Metalbone Youth 3.4 tackles an awkward problem in grassroots padel: most beginner rackets are round and soft, but kids want to smash. This padel racket takes the Octagonal Structure from the Metalbone family, wraps it in an oversize diamond shape at 345-360 grams, and fits a Soft Performance EVA core inside so the impact doesn't sting.

The result is a beginner racket with an attacking streak, aimed at the 8-14 age bracket with an aggressive playing style. This isn't a scaled-down club racket — it's a technical development design with a deliberately head-heavy balance.

Who should play with the adidas Metalbone Youth 3.4?

Beginner players aged 8 to 14 who already look to attack and don't want to sit back at the baseline. The lighter weight and soft rubber generate ball exit without needing consolidated technique, while the head-heavy balance and diamond shape keep that powerful-racket feel competitive juniors are after.

The sweet spot for this racket, so to speak, sits at the top end of that age range. A 12-14 year old with some physical development will get the most out of the head-heavy balance; an 8-year-old with a weaker arm will feel the racket pulling forward on defence.

Specs

Fibreglass and Soft Performance EVA: why this pairing is forgiving

A fibreglass face flexes more than a carbon face. That flex is exactly what a player who hasn't yet built racket-head speed needs: the racket does part of the work and sends the ball back with pace of its own.

The Soft Performance EVA core pushes in the same direction. It's a soft-feel rubber that compresses easily on contact, so the ball exit carries height and depth even on off-centre groundstrokes. On court, that means fewer balls dying in the net during the warm-up rally.

The trade-off is an honest one: with a soft core, fine depth control gets harder. On fast cross-court balls to the feet, the ball tends to run long unless the swing is shortened.

Octagonal Structure and Spin Blade 3D in a junior frame

Octagonal Structure is the signature tech of the Metalbone line: an octagonal frame profile that stiffens the structure without adding material in the impact zone. Here it does a different job than on the adult rackets — it's not chasing extra stiffness, it's stopping a lightweight frame from twisting on off-centre hits.

Structural Reinforcement backs that up. In practice, a young player who catches the ball two fingers off-centre won't feel the racket vibrate or twist in the hand — the number one reason a kid loses confidence with a racket.

Spin Blade 3D works together with the rough surface. On viboras and cut drop shots you can feel the ball hold onto the strings for an extra instant, and that instant is what lets a young player start to understand topspin and slice.

Smart Holes Curves round out the package: the hole pattern shapes mass distribution and stiffness across the face, and here it's tuned to keep the response lively in the upper face — right where the smash makes contact.

Shot by shot

Smash off the back wall and flat smash. This is its shot. The head-heavy balance drives the head through and makes up for the lack of overall weight: the junior player gets ball speed without needing a long swing.

Bandeja. Solid. Head inertia helps get up to the lob, though it demands earlier preparation than a round-shaped racket. Anyone late under the ball will feel the racket's weight pulling forward.

Vibora. The rough surface and Spin Blade 3D give enough grip to cut it, though the high impact zone of the diamond shape punishes mistimed hits.

Defence and wall exits. This is where it loses points. With the sweet spot stacked high, the lower face feels duller, and low wall exits come out with less depth than you'd want.

Volleys. Blocking volleys work well thanks to frame stability, but fine touch volleys ask for more precision than a soft core can give.

Who gets the most out of it

1. **Juniors aged 11 to 14** with an already-formed swing who want to move up to the net.
2. **Aggressive baseline players** who smash anything that sits above shoulder height.
3. **Tennis converts** who need extra ball exit while adapting their swing to padel.

It's not the racket for a kid who likes to sit back and build the point from the baseline — that player type will get more out of a round shape with a low balance.

As a doubles pairing, it fits well on the attacking backhand side — the finisher — leaving point construction to their partner.

Verdict: an attacking racket for players still learning how to attack

The Metalbone Youth 3.4 gets the important part right: it gives a beginner plenty of ball exit to play with confidence, while keeping the diamond geometry so that beginner can actually smash rather than just block the ball back.

Its limits sit exactly where you'd expect. Fine control isn't there, low defence comes up short, and the head-heavy balance demands anticipation. None of that is a flaw — it's the cost of a beginner racket that refuses to play it safe.

For a young player who wants to learn to attack without punishing their elbow, this adidas model offers a combination that's hard to find elsewhere in the junior segment.
