Grip Socks for Every Application

Nine made-to-order programmes in total — here are the six core applications, each with its own last, grip compound and grip layout. Any of them can be re-engineered to your specification.

Why CERTISOX

A Grip Sock Supplier That Removes the Risk

Buyers stay with us because three things never change: the grip stays on, the size stays true, and the shipment date holds.

Grip that passes wash tests

Silicone is screen-printed with a two-stage cure and pull-tested on every batch — no peeling after 50 home launderings.

In-house knitting & printing

Knitting, boarding, silicone printing, packing and QC all happen under one roof, so lead times don't depend on subcontractors.

Audited & certifiable

BSCI-audited, OEKO-TEX Standard 100 materials, ISO 9001 workflow. Test reports from SGS / Intertek available per shipment.

3–7 day sampling

Artwork today, physical sample in 3–7 days by DHL, with a full spec sheet so your team can evaluate before committing.

Low MOQ, real pricing

100 pairs per style/colour gets you factory-direct pricing and full customisation — viable for test launches and private label.

English-speaking team

Quotes within 12 working hours, dedicated merchandiser per account, and full photo / video updates during production.

Customization

Every Detail Is Yours to Specify

Six independent variables — combine them freely and we will build the tech pack around your brief.

1 · Yarn & Material

Combed cotton, organic cotton, bamboo viscose, merino blend, recycled polyester, or performance poly-spandex.

2 · Sizing

Newborn to adult XXL, EU / US / UK / Asia size charts, plus wide-calf and non-binding diabetic fits.

3 · Colour

Pantone-matched dyeing with lab dips for approval; heather, tie-dye and jacquard colour work available.

4 · Grip Pattern

Dot grid, wave, honeycomb, stripe, full-coverage tread, or a bespoke silicone mould shaped like your logo.

5 · Branding

Jacquard knit logo, silicone logo on the sole, woven label, printed care label, or embroidery on the cuff.

6 · Packaging

Bulk polybag, recyclable OPP, header card, kraft box, or retail-ready FSC cartons with barcode and FNSKU.

FAQ

Buying Questions, Answered

100 pairs per style, colour or size run for fully custom production. Mixed sizes inside one style are free of charge, and stock designs with your own label start from the same 100 pairs.
Sampling takes 3–7 days after artwork approval, plus 3–5 days for express shipping. Bulk production is 10–20 days after sample approval and deposit, depending on quantity and season.
Yes. We cut a bespoke grip mould from your vector artwork in either compound — PVC USD 50 or food-grade silicone USD 100 per design, refunded once the order passes 500 pairs.
Two compounds: food-grade silicone and phthalate-free PVC. Both pass OEKO-TEX Standard 100 and CPSIA; phthalate-free reports from SGS or Intertek can be issued for each production lot.
Vector files (AI, EPS, SVG or PDF) are preferred for grip layouts and logos. A hand-drawn sketch or a photo of an existing sock is also enough for us to build the first tech pack.
30% deposit with the order, 70% before shipment. T/T, L/C at sight and PayPal for sample fees. We ship EXW, FOB Ningbo / Shanghai, CIF or DDP by sea, air or express.
Absolutely. Send your NDA and we will sign it before any artwork is exchanged. Your designs and moulds are never shown to or reused for other clients.
