For spin class, wear fitted leggings or biker shorts, a supportive sports bra or fitted tank, and stiff-soled shoes: cycling shoes with the right cleat if your studio uses clip-in pedals, or firm sneakers if the bikes have toe cages. Bring a small towel and water, and leave loose running shorts, wide-leg pants and soft, squishy sneakers at home, because they rub on the saddle, flap near the pedals and waste your effort.
Spin class is an instructor-led indoor cycling workout on stationary bikes with a weighted flywheel, usually ridden in a dim room to loud music, with seated climbs, standing climbs and short sprints. You sit on a narrow saddle for most of the ride, then stand and lean forward over the handlebars when the music builds, and those two positions, together with a considerable amount of sweat, determine which clothing works and which clothing fails.
Spin class outfit at a glance
- Bottoms: fitted leggings or biker shorts that stay in position on the saddle and never flap near the pedals.
- Top: a supportive sports bra or a fitted tank that stays in place when you lean forward over the handlebars.
- Shoes: cycling shoes with the cleat your bike takes, or stiff sneakers for toe-cage pedals.
- Bring: a hand towel, a full water bottle, a hair tie and a dry top for afterward.
- Skip: loose shorts, wide hems, heavy cotton tees and soft, flexible running shoes.
Why fitted bottoms matter on a spin bike
On a spin bike, your bottoms do two jobs that a treadmill never asks of them: they sit between you and a narrow saddle, and they move next to a spinning crank and pedals. Cleveland Clinic names three root causes of saddle sores, which are friction, moisture and pressure, in its guide to preventing saddle sores. A spin class brings all three at once, so the goal is fabric that does not bunch, slide or hold sweat against your skin.
Loose fabric is the usual problem: running shorts ride up and bunch in the crease of your hip as you pedal, so the folds rub with every stroke, and wide-leg or flared pants can brush the crank or catch on a pedal strap. Fitted leggings or biker shorts move with your legs, which means there is no extra material to rub, twist or snag. SoulCycle gives the same advice on its studio FAQ, which suggests a tee or tank on top with form-fitting pants or shorts on the bottom.

The standing climb is the real test
When the instructor calls a standing climb, you rise out of the saddle and lean forward, and your seat becomes the most visible point in the room for the rider behind you, which is exactly the moment a thin pair turns sheer. Choose squat-proof leggings with four-way stretch, so the fabric stays opaque when it is stretched across your hips. A triangle gusset in the crotch also helps on the saddle, because the seams do not all meet at a single point under your sit bones, and a mid-rise or high waistband stays in place when you fold forward, so you are not reaching back to adjust it between songs.
Leggings, biker shorts or padded cycling shorts for spin class?
All three options work, and the right choice depends on how long you ride and how warm your studio usually feels. A chamois is the foam pad sewn into the seat of cycling shorts, made to soften pressure on the saddle during long rides. Biker shorts are the unpadded, everyday alternative, cut to a similar snug, mid-thigh length, and the table below matches each option to a particular kind of class.
| Your class | Best bottoms | Why |
|---|---|---|
| A 30 to 45 minute class in a cool room | Full-length leggings | Warmer at the beginning, no bare skin on the saddle, and they double as your everyday outfit afterward. |
| A hot, packed room or a sprint-heavy class | Biker shorts | Bare calves stay cooler, and the fitted leg will not ride up the way loose shorts typically do. |
| Back-to-back classes or a 60 minute endurance ride | Padded cycling shorts, or leggings with a gel seat cover | Additional time in the saddle means additional pressure, which is exactly what a pad is designed for. |
| Your very first class | Leggings you already trust | You will spend the ride learning the bike and the instructor's cues, so wear a pair you know will not slip or turn sheer. |
If you are still deciding between the two for other workouts, our guide on how leggings and shorts compare for running, lifting and the gym walks through the trade-offs. For spin, here is one print in both lengths, so you can switch with the seasons.
Both are made to order, and our FIERCE-Fusion technology fuses the design into the fibers, so the print will not crack or peel after a season of sweaty rides and washes. Browse every print in our leggings or our biker shorts.
What shoes to wear to spin class
The most important feature is a stiff sole. Peloton explains on its guide to cycling shoes that stiff soles keep your feet from bending while you pedal, and that the stiffer the sole, the more of your power reaches the bike. Soft running shoes flex over the pedal with every stroke, which can leave the arch of your foot aching by the end of class.
Your choice depends on the pedals: many gym bikes have a toe cage, which is a plastic basket with a strap that accepts any firm, flat-soled sneaker, while boutique studios usually install clip-in pedals that require cycling shoes with a cleat. A cleat is the small plastic or metal plate bolted to the sole of a cycling shoe that locks into the pedal, so your foot stays connected through every stroke until you twist your heel outward to unclip.
SPD vs Delta cleats: which one does your bike take?
Two cleat systems cover almost every spin bike, and because they are not interchangeable, ask the studio which one its pedals accept before you buy shoes.
Delta (3-bolt)
- A larger triangular plate attached with three bolts.
- Used on Peloton bikes and required at SoulCycle.
- Red cleats allow 9 degrees of float; black cleats allow none.
- Needs a road-style shoe with three holes in the sole.
SPD (2-bolt)
- A smaller metal cleat attached with two bolts.
- The most common system on shoes and pedals.
- Fits many gym bikes with dual-sided pedals.
- Needs a shoe with two slots in the sole.
Peloton notes that 2-bolt shoes and pedals are the most common, while its own bikes use the larger 3-bolt Look Delta system, in the same cycling shoe guide. SoulCycle requires clip-in shoes with Look Delta cleats, says its pedals can also take SPD cleats, and rents shoes in every size for $4.00 in the US, according to its FAQ. LOOK lists its Delta cleat for road and indoor bikes with 0 degrees of float in black and 9 degrees in red on its cleat product page. Float is the small side-to-side twist your heel can make while clipped in, so the red version gives your foot a little room to move.
Our advice is to rent shoes for your first two or three classes, then buy a pair once you know you will keep riding, and to consider indoor cycling shoes with holes for both systems, which keeps your options open if you change studios. For what to wear on your feet once you leave the studio, see our guide to shoes to wear with leggings.
What to wear on top for spin class
Choose your top for the standing climb rather than the warm-up, because when you lean forward over the handlebars a loose tee hangs open at the neck and slides up your back, and a heavy cotton shirt absorbs sweat and stays wet for the rest of class. A supportive sports bra keeps you comfortable through standing sprints, and a fitted tank over it covers your back if the studio asks for a shirt, as SoulCycle does.

Matching your top to your bottoms is simple when you choose a print. On October 30, 2026, we counted 481 designs in our biker shorts and 931 in our sports bras from our store's product data, filtered by exact product type, and prints such as Leopard and Blue Majolica come in both. Our sports bras run XS to 2XL at $64.99, and the racerback styles shown here stay put when you are out of the saddle.
How to handle the sweat
A spin class gets sweaty fast, because the room is full of riders working hard in the same air. Wear moisture-wicking fabric on top and bottom, and drape a hand towel over the handlebars so you can wipe your face and grips between songs. Cleveland Clinic advises changing out of bike shorts right after you ride and avoiding sweaty clothing, which can irritate the skin, in the same saddle sore guide. Pack a dry top and a change of bottoms if you are heading somewhere afterward.
The effort is worthwhile: federal guidelines say adults need at least 150 to 300 minutes of moderate-intensity aerobic activity each week, according to the Office of Disease Prevention and Health Promotion, and a few spin classes a week go a long way toward that number. An outfit you trust makes it easier to keep showing up consistently.
What to wear to spin class if you are plus size
The saddle rules are the same in every size: a fitted pair, a high waist and no extra fabric at the hip crease. Our plus size line is its own range, sized 2XL to 6XL at $89.99 with a high-rise waistband, such as the Blue Majolica Plus Size Leggings. A gel seat cover from the front desk can make the saddle more comfortable too. Browse every print in our plus size leggings.
Frequently asked questions
What should I wear to my first spin class?
Wear fitted leggings or biker shorts, a supportive sports bra or fitted tank, and firm sneakers, or rent cycling shoes at the studio. Bring a towel and water, and skip loose shorts and cotton tees, because they bunch on the saddle and hold sweat.
Is it better to wear leggings or shorts to spin class?
Fitted leggings and fitted biker shorts both work: leggings suit cool rooms and first classes, while biker shorts suit hot, crowded rooms. Avoid loose running shorts, which ride up and rub as you pedal.
What shoes should you wear to spin class?
Wear stiff-soled shoes, since clip-in pedals need cycling shoes with the right cleat, usually Delta (3-bolt) or SPD (2-bolt), and toe-cage pedals work with firm, flat sneakers. Most boutique studios rent cycling shoes for a small fee.
Do I need padded shorts for spin class?
Not for a standard class, because most riders are comfortable in fitted leggings or biker shorts, although padded cycling shorts help on long or back-to-back rides, when time in the saddle adds up.
What should you not wear to spin class?
Avoid loose running shorts, wide-leg or flared pants that can catch near the pedals, heavy cotton shirts, soft running shoes and dangling jewelry. Anything that bunches, flaps or soaks through will distract you in the middle of a ride.
What is the difference between SPD and Delta cleats?
Delta cleats are larger triangles held by three bolts and are used on Peloton and SoulCycle bikes. SPD cleats are smaller and held by two bolts, and since neither fits the other's pedals, check with your studio before you buy.
Fitted, opaque and ready for the climb.
