Engineered From the Hardwood Up

Every knit zone solves a real complaint from full-court players—from midsole slippage to post-wash stiffness.

3.8mm Heel & Toe Impact Terry

High-density combed cotton loops under the heel and forefoot soften hard rebounds and two-hour coaching or pickup runs.

6 Woven Sole Grip Channels

Raised transverse ribbing grips your sneaker's sockliner to stop forefoot micro-slides on step-backs and lateral slides.

360° ZIMOSE Arch Lockdown

Jacquard-woven elastic midfoot band hugs your arch so fabric never twists or scrunches inside snug basketball shoes.

Diamond Open-Mesh Instep

Breathable top-of-foot ventilation channels vent heat and sweat out through the sneaker tongue to prevent damp blisters.

3 Knit Zones That Lock Your Foot to the Court

1. Underside Ribbed Traction & Terry Cushion

1. Underside Ribbed Traction & Terry Cushion

Six raised woven sole grip lines work with 3.8mm plush terry heel and toe pads to brake lateral foot movement inside your shoe—without sticky silicone dots that snag on insoles.

2. ZIMOSE Arch Band & Breathable Mesh Instep

2. ZIMOSE Arch Band & Breathable Mesh Instep

A firm black woven elastic band wraps 360 degrees around the midfoot to eliminate toe-box bunching, paired with an open diamond-mesh top panel that dumps trapped heat.

3. Stay-Up 7" Ribbed Cuff & Flat-Knit Toe

3. Stay-Up 7" Ribbed Cuff & Flat-Knit Toe

Vertical calf ribbing holds a crisp mid-calf silhouette through four quarters of sweat, while the recessed flat-knit toe seam prevents raw pinky-toe chafing.

Description

Built to Fix Midsole Slippage: Even $180 signature hoop shoes can't hold your foot if worn-out synthetic socks slide across the insole. CourtLock Pro uses 6 woven sole traction channels and a 360° ZIMOSE arch band to keep your foot planted on every crossover and hard stop.

Combed Cotton Loft That Survives the Washer: Big-box 95%-polyester socks bake into stiff, slippery shells after five washes. Our 78% long-staple combed cotton, 17% breathable polyamide, and 5% recovery elastane blend keeps 94% of its 3.8mm cushion bounce through repeated cold washes.

Honest Fit & Break-In Notes: Engineered for US Men's 7–12 (Women's 8.5–13.5); players in size 13+ will find the heel pocket snug. Because of the dense 3.8mm underfoot padding, allow 15 minutes on your first wear for the terry loops to mold inside tight performance sneakers.

My new go-to basketball socks

Best basketball socks I've owned. The cushioning feels awesome, the ribbed arch and sole wrap my feet without sliding, and the calf cuff stays snug. They've held up well so far too.

Great for long coaching days

These are easily the most comfortable socks I wear while coaching. The extra cushioning under the heel and forefoot makes hours on the court much easier on my feet. I keep reaching for them.

Already ordered another pack

Honestly the best athletic socks I've worn. Comfortable, supportive, and not bulky inside my shoes. I liked the first 4-pack so much that I ordered another one online.

Clean look with real support

Great fit and support through the arch, and the extra cushioning around the heel and sole feels excellent on court. The matte white ribbed cuff and small black ZIMOSE detail look clean too.

Holding up in heavy rotation

I've had these in heavy rotation for several months, with plenty of practices and washes, and they're still in great shape. The reinforced areas feel durable, and the cushioning hasn't flattened out like my cheaper socks.

Quality is exceptional

Excellent quality and comfort. I spent way too long comparing athletic socks, but these feel well made from the cuff down to the woven ribbed sole. If you're debating the purchase, just get them.

Extremely comfortable

These may be the most comfortable socks I've ever worn. The cotton-blend knit feels soft, and the cushioned footbed is excellent without feeling overly bulky.

Better than the stiff pairs

These ZIMOSE crew socks are hands down my favorite right now. They're softer and more comfortable than the stiffer athletic socks I've been buying, but still feel snug enough for basketball.

Smooth around the toes

I've owned pricier name-brand basketball socks, but the toe stitching on these feels cleaner and smoother inside my shoes. No annoying seam pressing against my toes, and the reinforced toe still feels substantial.

Better everyday court value

I got tired of paying for overhyped big-brand basketball socks that stiffened after repeated washing. This cotton-blend 4-pack feels softer, cushions just as well for everyday runs, and is a much better value.

Frequently Asked Questions

How many pairs come in one order for $29.99?

Each order includes one complete 4-Pack—that is 4 full pairs (8 individual matte-white crew socks), working out to $7.50 per pair with today's 50% discount.

What exact shoe sizes do the Cosari CourtLock Pro socks fit?

They are engineered for US Men's shoe sizes 7–12 (US Women's 8.5–13.5 / EU 40–46). Because of the firm 360-degree arch band and contoured heel pocket, players wearing Men's size 13+ will find them snug.

Do these have sticky rubber dots on the bottom or woven ribbing?

Woven ribbing. We use 6 raised transverse cotton-blend grip channels knitted directly into the sole—never glued-on silicone dots that peel off in the dryer or catch on insoles when pulling your shoes on.

Will they shrink or turn stiff and crusty in the washer?

No. Our pre-shrunk 78% combed long-staple cotton blend retained 94% of its 3.8mm heel cushion loft after 10 test washes. Machine wash cold without fabric softener and tumble dry low.

How high do they sit on the leg, and will they slide down?

They sit at a classic 7-inch (18cm) mid-calf athletic crew height. Vertical elastane ribbing runs down the entire leg shaft to hold the cuff cleanly in place without pinching or sagging.

How does the 30-Day Money-Back Guarantee work?

Lace up a pair, play pickup or league games, and wash them. If they bunch at the toes, slide down your calf, or don't feel better than your $18 store socks within 30 days, contact our team for a full $29.99 refund.
