Sizing Note for B2B Buyers
JP sizing uses cm foot length directly (e.g. 24 cm = size 24). Korean sizing follows a similar convention. For AU markets, women's sizes typically run 1.5 sizes larger than US. Always request a pre-production size confirmation sample when entering a new market.
Fit Recommendation
Grip socks should fit snugly without bunching. A sock that is too loose will cause grip dots to misalign and reduce anti-slip performance.
Size Range Selection
For studio retail, S/M/L is the standard 3-size range. For trampoline parks, adding XS (kids) and XL (large adults) reduces customer complaints.
Market-Specific Labeling
EU buyers often prefer cm-based labels. US buyers prefer US shoe size ranges. JP/KR buyers expect cm foot length. Confirm label format during artwork approval.
Section 02
Material Structures
The base knit material determines comfort, stretch, durability, and moisture management. Choosing the right material structure is critical for end-user satisfaction and product positioning.
Most Common
Cotton Blend
Typically 60-80% cotton with nylon and spandex. Soft, breathable, and affordable. Best for Pilates, yoga, and barre studios where comfort and feel are priorities.
Performance
Nylon / Polyester Blend
High-tenacity synthetic fibers with spandex. Excellent durability, stretch recovery, and quick-dry performance. Preferred for trampoline parks, sports, and high-frequency use environments.
Premium Option
Bamboo / Modal Blend
Ultra-soft natural-derived fibers with excellent moisture-wicking and anti-odor properties. Ideal for premium fitness brands and eco-conscious buyers targeting boutique markets.
Cushioned
Terry Loop Cushion
Terry loop knit structure on the sole interior. Adds padding and impact absorption without increasing sock weight significantly. Common in medical, hospital, and sports recovery socks.
Breathable
Mesh Knit Structure
Open-mesh panels on the upper foot or leg area improve airflow and reduce heat buildup. Often combined with a solid sole for grip application. Popular in summer collections and warm-climate markets.
Key Specification
Thickness & Elasticity
Sock weight (thickness) and elasticity directly affect fit, feel, and grip dot adhesion. Specify these during product development.
Thin (Light Weight)
Ideal for Pilates, yoga. Lightweight feel, good floor sensitivity, suits warmer studios.
Mid-Weight (Standard)
Most versatile. Suitable for trampoline parks, barre, and general fitness. Balances comfort and durability.
Thick / Terry Cushion
Best for medical and hospital use. Adds padding, reduces pressure points, supports elderly users.
Elasticity (Spandex %)
3-5% spandex for standard stretch. 8-12% for compression or snug-fit styles. Higher spandex improves grip dot contact with the floor surface.

Grip Technology Explained
The anti-slip coating is the defining feature of grip socks. Understanding the two main technologies -- silicone and PVC print -- helps buyers specify the right product for their application and market.
Premium Choice
Silicone Grip
Silicone dots or patterns are applied via a heat-press or injection molding process. The result is a raised, three-dimensional grip surface that provides superior traction on smooth floors -- wood, PVC, rubber, and tile.

Washing & Care Instructions
Correct washing extends grip sock lifespan significantly. These guidelines apply to silicone and PVC grip socks. Share them with your end customers via packaging inserts or care labels.
Step-by-Step Care Guide
Wash Temperature
Machine wash cold or warm -- maximum 30°C (86°F). High heat weakens the silicone bond and causes grip dots to peel or crack. Never wash at 60°C or above.
Turn Inside Out
Turn socks inside out before washing. This protects the grip dots from friction against other garments in the drum and extends the life of the anti-slip surface.
Detergent Selection
Use mild, liquid detergent. Avoid bleach, fabric softener, and enzyme-based detergents. Softener coats the grip surface with a residue film that reduces traction over time.
Drying Method
Air dry flat or hang dry only. Do not tumble dry. High dryer heat degrades silicone adhesion rapidly. Avoid direct sunlight for extended periods -- UV exposure can yellow silicone over time.
Do Not Iron or Dry Clean
Never iron over grip dots -- direct heat melts silicone. Dry cleaning solvents dissolve PVC and silicone adhesives. Ironing is not required; grip socks are designed to be worn without pressing.

Frequently Asked Questions
Common questions from B2B buyers about sizing, materials, grip durability, and ordering.
What is the minimum order quantity for custom grip socks?
Our standard MOQ starts at 100-300 pairs per style/color for custom logo printing on stock styles. For fully custom developed styles (new knit structure, unique grip pattern, custom packaging), MOQ typically starts at 300-500 pairs. Exact MOQ depends on the complexity of customization -- contact us with your project details for a precise quote.
How do I choose between silicone and PVC grip for my product?
Choose silicone if: you're targeting premium fitness studios or retail, you need 50+ wash durability, or your buyers are price-tolerant and value quality. Choose PVC if: you're supplying high-volume trampoline parks or budget-tier markets, cost per unit is the primary concern, and the socks will be used for a limited number of sessions. When in doubt, silicone is the safer long-term choice for brand reputation.
Can I order multiple sizes in a single purchase order?
Yes. A typical order includes S, M, and L in a set ratio (e.g. 20% S / 60% M / 20% L). The MOQ applies to the total order, not per size. You can specify your own size ratio based on your market -- we recommend requesting a size breakdown consultation if you're entering a new market, as size distribution varies significantly between US, EU, and Asian markets.
How many washes before grip performance degrades noticeably?
With correct care (cold wash, no softener, air dry), silicone grip socks maintain strong performance for 50+ washes. PVC grip socks typically maintain good performance for 20-35 washes. The most common cause of early grip failure is tumble drying or using fabric softener -- both should be clearly communicated on your care label and packaging insert.
Do you provide size charts for packaging and labeling?
Yes. We provide market-specific size chart templates for US, EU, UK, AU, JP, and KR markets. These can be incorporated into your hang tag, polybag insert, or box packaging. We also support multi-language care labels. All artwork is reviewed during the pre-production sample stage before bulk production begins.
What is the lead time for samples and bulk production?
Sample lead time is 7-10 business days for approved projects with confirmed specifications. Bulk production lead time is 25-35 days after sample approval and deposit payment. Timelines may vary during peak seasons (Q3-Q4). We recommend beginning the sampling process at least 8-10 weeks before your target delivery date for first-time orders.
Can I get grip socks with both a custom grip pattern and custom logo?
Yes. We support full customization including: custom grip pattern shape (e.g. logo-shaped silicone dots), woven or embroidered logo on the sock upper, custom color matching, and branded packaging. For logo-shaped grip dots, a minimum quantity and pattern complexity review applies. Send us your logo file and we will advise on feasibility and cost during the quotation stage.
What shipping options are available and what are typical landed costs?
We ship FOB Ningbo (standard) and DDP (Delivered Duty Paid) to major markets including EU, US, CA, AU, JP, and KR. DDP simplifies customs clearance for buyers who prefer a single all-in landed cost. For small sample orders, express courier (DHL/FedEx) is used. For bulk orders, sea freight (LCL or FCL) is recommended. We provide freight cost estimates during quotation.
