If you are going to your first reformer Pilates class, one of the most common questions is simple:
What socks should I wear?
The short answer: wear grip socks.
Reformer Pilates uses a moving carriage, springs, straps, a footbar, shoulder blocks, and platforms. Your feet are often pressing, holding, stabilizing, or balancing on different surfaces. Regular socks can feel slippery, especially during footwork, planks, bridges, lunges, scooter, and standing exercises.
Grip socks are designed to give you better traction than regular socks. Many studios also require them for hygiene and safety reasons. Club Pilates, for example, says all class participants need grip socks, and BODYBAR Pilates says its studios require grip socks with non-slip soles for safety and hygiene.
But not all grip socks are the same.
Some only grip the reformer. Others, like BOLD Dual Grip Socks, are designed to help your foot stay secure inside the sock while the sock grips the reformer, mat, or floor.
That difference matters more than most beginners realize.
Quick answer
For reformer Pilates, wear socks with:
- Non-slip grip on the sole
- A secure fit that does not twist or bunch
- Breathable fabric
- Enough grip coverage from toe to heel
- A closed toe or toe sock style, depending on preference
- Ideally, inside grip if your foot slides inside regular grip socks
Avoid regular cotton socks. They are usually too slippery for reformer work.
A good Pilates sock should help you feel stable, grounded, and focused so you can think about the movement instead of your feet.
Why reformer Pilates requires better socks
Reformer Pilates is different from a regular mat workout.
The machine moves. The springs create resistance. Your feet may be on the footbar, carriage, platform, straps, floor, or shoulder blocks. In many exercises, your body is trying to control movement while the carriage shifts underneath you.
That is why traction matters.
If your socks slip, you may start gripping with your toes, adjusting your stance, or holding back from the movement.
Mayo Clinic Press also notes that Pilates socks are recommended for reformer Pilates because your feet are used to balance on different surfaces of the reformer machine.
Do studios require grip socks?
Many reformer Pilates studios do require grip socks, but policies vary by studio.
Some require them for every class. Some strongly recommend them. Some sell them at the front desk if you forget a pair.
The safest approach is to bring grip socks to your first class.
Even if your studio does not strictly require them, they are still useful because they help with:
- Traction
- Hygiene
- Stability
- Comfort
- Confidence on the reformer
- Reduced slipping during transitions
If you are unsure, check your studio's FAQ before class.
Can you wear regular socks to reformer Pilates?
Regular socks are not ideal for reformer Pilates.
They may feel fine while walking into the studio, but once you are on the machine, they can slide on the carriage, platform, or floor.
Regular socks also usually have no grip inside the sock. That means your foot can move inside the sock during exercises, even if the sock itself stays mostly in place.
This is why many people feel unstable in class and assume they are doing something wrong. Sometimes the issue is just the sock.
Can you go barefoot?
Some studios may allow barefoot mat Pilates, but many reformer studios prefer or require grip socks.
Bare feet can provide direct contact with the equipment, but studios often prefer socks for hygiene. Grip socks create a cleaner barrier between your foot and shared equipment while still giving you traction.
For reformer Pilates, grip socks are usually the better default.
What kind of grip socks are best for reformer Pilates?
The best reformer Pilates socks should be built for control.
Here is what to look for.
1. Full sole grip
Look for grip coverage across the sole, not just a small patch under the ball of the foot.
In reformer Pilates, your foot position changes constantly. Sometimes you are pressing through your heels. Sometimes through your toes. Sometimes through the full foot.
Toe-to-heel grip gives you more useful traction across more movements.
2. A secure fit
A good Pilates sock should feel snug, but not tight.
If the sock is too loose, it can twist, bunch, or slide forward. If it is too tight, it can feel uncomfortable during class.
The sock should stay close to your foot and move with you.
3. Breathable fabric
Reformer Pilates can still make you sweat.
Breathable or moisture-wicking fabric helps keep your feet more comfortable during class. This is especially important for Lagree, heated studios, or higher intensity reformer classes.
4. Grip that works during pressure
A reformer sock needs to perform when your foot is under tension.
Footwork, planks, pikes, bridges, scooter, and lunges all create pressure through the feet. Weak grip can feel fine at the start of class, then become distracting once the movement gets harder.
5. Inside grip if your foot slips inside the sock
This is the feature most people do not think about.
Most grip socks only have traction on the outside sole. That helps the sock grip the reformer.
But your foot can still slide inside the sock.
Dual grip socks are designed to solve both slipping points:
Inside grip: helps your foot stay secure within the sock
Outside grip: helps the sock connect to the reformer, mat, or floor
That is the main difference between regular grip socks and BOLD Dual Grip Socks.
Maria's instructor note
Maria, co-founder of BOLD and a certified Pilates and Lagree instructor, noticed that many clients were not only slipping on the reformer. Their feet were sliding inside their socks.
The sock would grip the machine, but the foot inside the sock would still shift.
That small movement can make you curl your toes, adjust your foot position, or lose focus during a set.
That is why BOLD was designed with grip on both sides. The goal is simple: your foot grips the sock, and the sock grips the reformer.
Closed toe, open toe, or toe socks?
There are a few common sock styles for reformer Pilates.
Closed toe grip socks
Closed toe socks feel most like traditional socks. They are usually easy to wear, comfortable, and beginner friendly.
Best for:
- Reformer Pilates
- Lagree
- Barre
- Yoga
- Studio fitness
- People who want full foot coverage
BOLD uses a closed toe crew design because it gives a classic sock feel while still supporting performance.
Toe socks
Toe socks separate each toe. Some people like them because they allow more toe articulation and a barefoot-style feel.
Best for:
- People who like toe separation
- Yoga
- Pilates users who want more foot articulation
- People who dislike fabric between toes should avoid them
Toe socks are personal. Some people love them. Others find them uncomfortable.
Open toe socks
Open toe socks leave the toes exposed while still adding some grip and coverage.
Best for:
- People who want more toe freedom
- Barre
- Yoga
- Warmer studios
- Users who dislike full toe coverage
For reformer Pilates, closed toe or toe socks are usually the easiest choice for beginners.
What should beginners wear to reformer Pilates?
For your first reformer Pilates class, choose:
- Grip socks
- Fitted leggings or shorts
- A fitted top
- No loose clothing that gets caught in equipment
- Minimal jewelry
- Hair tied back if needed
- A water bottle
For socks, do not overthink the style too much. Just make sure they have good grip and fit securely.
If you already know your feet slide inside socks, choose dual grip.
What not to wear on your feet
Avoid:
- Regular cotton socks
- Thick winter socks
- Loose socks
- Socks with no grip
- Slipper socks with bulky soles
- Shoes
- Socks that bunch under your arch
- Worn-out grip socks with smooth traction
Grip socks should feel like part of your movement, not something you are fighting.
Do you need different socks for Lagree?
You can often wear the same grip socks for reformer Pilates and Lagree.
But Lagree usually feels more intense. The holds are longer, the transitions can be faster, and your muscles fatigue more quickly.
For Lagree, you may want a sock with:
- Stronger grip
- Better breathability
- More secure fit
- Toe-to-heel traction
- Inside grip
That is why BOLD Dual Grip Socks work well across both reformer Pilates and Lagree.
Why your foot may still slide in grip socks
If you already wear grip socks but still feel unstable, there are a few possible reasons.
The sock only grips outside
This is the most common issue.
The sock grips the reformer, but your foot slides inside the sock.
The sock is too loose
A loose sock can twist, bunch, or move with your foot.
Your feet are sweaty
Moisture can reduce the connection between your skin and the sock fabric.
The grip is worn down
Grip socks lose tackiness over time, especially if washed or dried improperly.
The grip coverage is too limited
Small grip patches may not be enough for reformer movements that use the whole foot.
Single grip vs dual grip for reformer Pilates
| Feature | Single Grip Socks | Dual Grip Socks |
|---|---|---|
| Outside sole grip | Yes | Yes |
| Inside grip | Usually no | Yes |
| Helps sock grip reformer | Yes | Yes |
| Helps foot stay secure inside sock | Limited | Yes |
| Best for | General Pilates, barre, casual use | Reformer Pilates, Lagree, stronger grip needs |
| Feel | Sock grips surface | Foot grips sock, sock grips surface |
Single grip socks can be enough for many people.
Dual grip socks are more useful if your foot slides inside the sock or you want a stronger locked-in feeling on the reformer.
Are expensive Pilates socks worth it?
Not always.
If you take reformer Pilates once in a while, a basic grip sock may be fine.
If you go weekly, take Lagree, teach classes, or feel your feet slipping, a better sock can make class more comfortable and less distracting.
The best sock is not necessarily the most expensive one. It is the one that fits well, grips well, washes well, and supports the way you move.
What socks does BOLD recommend?
For reformer Pilates, BOLD recommends dual grip socks with:
- Grip inside the sock
- Full sole grip outside the sock
- Moisture-wicking fabric
- A secure crew fit
- Toe-to-heel traction
- A design built for Pilates, Lagree, barre, and yoga
BOLD Dual Grip Socks were created because regular grip socks did not fully solve the slipping problem. We wanted a sock that helped with the full connection:
Foot to sock. Sock to reformer.
Final thoughts
For reformer Pilates, the best socks are grip socks that help you feel secure, comfortable, and focused.
Regular socks are usually too slippery. Bare feet may not be allowed. Basic grip socks can work, but they may not stop your foot from sliding inside the sock.
If you are new to reformer Pilates, start with a good pair of grip socks.
If you already know your feet slip inside regular grip socks, choose dual grip.
Your socks should help you feel grounded through every move, not distract you from the class.
