Legs in barna flow grip socks mid-exercise on a Pilates reformer

Our story · Barcelona, since 2026

We couldn't find grip socks that stayed put. So we made them.

Barna flow makes Pilates grip socks and mulberry silk scrunchies in Barcelona, for the reformer, the mat and the barre.

Where it started

Most grip socks give out before the class does.

The usual story: a few months of washing and the grip starts to lift. The sock slides on the footbar, bunches at the heel, and you spend the rest of the class pulling it back into place.

So we started with the parts that fail. Silicone fused into the fabric across the whole sole, not printed on top. A reinforced heel and a band through the arch. An organic combed cotton blend, soft enough for a long flow and structured enough to hold its shape wash after wash.

Then we made them something you'd want to wear: the ruffle cuff, the embroidery, the colour.

Then we went after the last bit of slipping. Regular grip socks grip the floor, not your foot, so on the footbar your foot can still slide around inside the sock. Our Double-Lock™ Grip socks have silicone on both sides of the sole: the floor grip locks the sock down, the inner grip locks your foot in.

Barna flow started in Barcelona in early 2026, and the city is still where every pair begins and ships from.

You should feel put together before you've even stepped onto the mat.

Double-Lock^™ Grip

Most grip socks grip the floor. Ours grip your foot too.

Nothing slides. Nothing twists. No stopping mid-class.

1 · Locks your foot in
Inner grip
Silicone inside the sole holds your foot still, so it can't slide around in the sock.
2 · Locks the sock down
Outside grip
Silicone outside anchors the sock to the reformer, the mat and the floor.
3 · Both sides
Triangle grip shape
Both layers are set in triangles across the sole.

What we kept finding

Grip socks were an afterthought. We didn't think they should be.

The grip gives out first
Most grip socks print their dots on top of the knit, so a season of washing is enough to lift them. Ours is silicone fused into the fabric across the whole sole, rated for 150+ washes.
Studios ask for them
Many reformer studios ask you to wear grip socks on shared equipment. If you practise every week, the pair on your feet should be one you trust on the carriage, the footbar and the studio floor.
They should look like they belong
The cuff, the colour, the embroidery placement, the weight of the fabric against you. Pulling on a pair before class is part of the ritual, so we sweat those details.

The name

Barna, for Barcelona. Flow, for the class.

Barna is what locals call Barcelona, the city every pair is designed in and dispatched from.

Flow is the part of a good class you can't rush: slow, controlled, precise. A calm studio, not a loud gym. That's the feeling we design for.

What it actually is

Not your usual grip sock. That's the point.

A grip sock looks simple until you've worn out a few. These are the things worth checking on any pair, and where ours stand.

What we stand for

A few things we won't budge on.

We'd rather you know exactly what you're buying, and who you're buying it from.

A breathable, temperature-regulating blend that stays soft through a full class.
Grip that's fused, not printed
Silicone across the whole sole, fused to the fabric and rated for 150+ washes.
22 momme mulberry silk

Behind the brand

The questions people ask us.

Who we are, where we work from and what happens after you order.

Why grip socks?

Because we couldn't find a pair that stayed put. Pilates is slow, precise work, and a sock that slides on the footbar or bunches at the heel pulls you out of it. We wanted grip you could stop thinking about.

Where are you based?

Barcelona. Ivana started barna flow here in early 2026, and every order still ships from the city within 24–48 hours, tracked across Europe and the UK.

Who are they for?

Anyone who practises regularly, on the reformer, the mat, at the barre or in a yoga class, and the studios and instructors who teach them.

Do you work with studios and instructors?

Yes. If you run a studio or teach classes, email contact@barnaflow.com and we'll tell you how it works.

What sizes do you make?

Our grip socks are one size, with a snug stretch fit that adapts to your foot. No sizing chart to decode.

What if they're not right?

Return unused items in their original packaging within 30 days of delivery. Email contact@barnaflow.com and we'll take care of you.

These socks are sooo cute🩷, I’m obsessed with the coffee + pink combo, it gives cozy girl vibes but still looks stylish in class. Super comfy, great grip.

My fave socks for lagree! very soft and stable

LucíaCoffee, Pilates & Self-Care Grip Socks
Amazing quality and grip. Comfortable and they look great. I love the palm aesthetic. Suitable for all types of workouts, not just pilates.

MinaBarcelona Palm Pilates Grip Socks
🩷 This is my second order! I really liked my first pair, so I wanted to try the new designs too. I love the grips on both sides, they help me feel more stable on the reformer. And the new...

Jia Verified buyerHearts & Stripes Pilates Grip Socks
Cute socks. I wear the beige colour to reformer 3 times a week and they still look good after loads of washes. The grip is solid even on the jump board.

Sofia M.That Girl Pilates Grip Socks
Great through standing work
dull but useful detail: the sock never rotates on my foot. combined with the strong hold, that is the whole appeal

Teresa L.You Can Do It Pilates Grip Socks
Dots and grip perfection
fan of the look, and the return instructions were refreshingly clear (didnt need them). colour reads cooler online than in my room. subtle differences day to day, but the grip shows up when class gets demanding - another colour ordered

Filipa C.Cocoa Polka Dot Pilates Grip Socks
Secure the whole session
40+ wears in. the anti-slip bottom pulls its weight - grippiest on the reformer, slightly softer on the mat. details are well finished

Eva M.Pawlates Pilates Grip Socks
Very good quality and pretty design. Shipping to Germany took a few days longer than I expected, but worth the wait.

Anna K.Coffee, Pilates & Self-Care Grip Socks
Grip held up nicely
wear number fifty. steady the entire class, moving up from kneeling needs no sock adjustment at all, and the finishing touches are tidy

Anca M.Barcelona Palm Pilates Grip Socks
My everyday studio pair
50+ wears probably . reformer footwork feels locked in the whole series. yes, I caved and bought the other colour too

Patrycja K.Hearts & Stripes Pilates Grip Socks
LOOKS CUTE, WORKS HARD
152nd wear. the print keeps its slightly imperfect charm up close, and the little details have worn well
