Quick answer: A sock goes through 5 production steps: yarn preparation, knitting (96-200+ needles), toe seam (overlock, flat or hand-linking), dyeing/finishing and quality control. The needle count of the knitting machine determines quality most — 200 needles create a premium stitch pattern.
Before a sock can be knitted, the yarn must be prepared. With bamboo viscose, bamboo pulp is chemically converted into spinnable fiber (viscose process). This fiber is spun and wound into yarn balls. With cotton, raw cotton is cleaned, combed (with premium quality, short fibers are removed) and spun. The finished yarn already contains the intended material blend — e.g. 78% bamboo viscose, 17% polyamide, 5% elastane. The different fibers are twisted together during spinning.
Modern socks are made on circular knitting machines — cylinders with needles that form stitches in split seconds. The needle count is the most important quality factor:
| Needle Count | Quality | Surface | Segment |
|---|---|---|---|
| 96-128 | Standard | Visible stitches, rough | Discount, multipacks |
| 144-168 | Fine | Smoother, less friction | Mid-range |
| 200+ | Premium | Silky-smooth, no gaps | SOKKS, High-End |
The knitting machine builds the sock from top to bottom — cuff, leg, heel, foot, toe area. Reinforcements at heel and toes are incorporated through automatic yarn changes or double knitting. A 200-needle machine takes more time per sock than a 96-needle machine — this explains the price difference between discount and premium socks.
After knitting, the sock has an open area at the toe tip that must be closed. Three methods:
Overlock seam: The fastest and cheapest method. A machine sews the two sides together and creates a raised ridge. This ridge is noticeable in the shoe — a potential blister source with 10,000 steps per day. Standard for discount socks.
Flat seam: The seam is laid flat on the fabric — much less noticeable. Medium effort and cost.
Hand-linked toe: The highest quality method. Each stitch is individually connected — no pressure point is created. This work step accounts for up to 30% of a sock's production time. SOKKS uses hand-linked toes for maximum wearing comfort.
After knitting, the sock is dyed, washed and finished. Premium manufacturers dye the yarn before knitting (yarn dyeing) — this produces more even and durable colors than dyeing the finished sock. The Oeko-Tex Standard 100 test examines the final product after dyeing for over 350 harmful substances — including problematic dye residues.
Every sock is checked for defects before packaging: stitch evenness, seam quality, color accuracy, elastane function (cuff test), and visual inspection for weaving defects or thread breaks. At SOKKS, every batch is additionally tested for Oeko-Tex Standard 100 requirements — freedom from harmful substances is not a one-time test, but an ongoing process.
The costs lie in three factors: First, better materials — bamboo viscose costs more than polyester, combed cotton more than uncombed. Second, slower production — 200 needles need more time than 96, hand-linking more than overlock. Third, quality control and certification — Oeko-Tex testing, regular laboratory analyses and stricter rejection criteria cost money. At SOKKS, this results in a price of €4.98 per pair (€19.90 for 4 pairs) — and the 6-month anti-hole guarantee shows that this investment in quality pays off.
Bamboo viscose: Bamboo is harvested, processed into pulp, and spun into fiber through the viscose process. Cotton: Harvesting the bolls, ginning, cleaning and combing the fibers.
Fibers are spun into yarn — the yarn fineness determines sock quality. Finer yarn produces softer, denser socks.
The needle count determines knitting density: 100-140 needles (discount) vs. 200 needles (SOKKS Premium). More needles mean finer stitch pattern and better durability. Different zones are made with different knitting techniques.
Overlock (fast, raised ridge), flat seam (more complex, flat) or hand-linking (manual, finest method). SOKKS uses flat seams.
This is where Oeko-Tex becomes relevant: The certification tests the final product after dyeing for harmful substance residues.
Visual inspection, size sorting and packaging in 4-packs.
200 needles vs. 100 needles: Twice as many threads per square centimeter. Each thread bears half the load — double the durability. Finer stitch pattern — softer feel and smoother surface. SOKKS: 200 needles, bamboo viscose, Oeko-Tex Standard 100, 6-month guarantee. 4 pairs from €19.90.
Between production and sale stands quality control: Visual inspection for knitting defects, color deviations and seam errors. Measurement control (is the size correct?). And for Oeko-Tex certified products: Regular laboratory tests for over 350 harmful substances. SOKKS goes through this quality process for every batch — the certificate is renewed annually.
The quality of a sock is decided in production — not in marketing. 200-needle knitting machines are more expensive than 100-needle machines. Flat seams require slower production than overlock. Oeko-Tex certification costs laboratory tests and audits. These investments in production make the price difference between €1 discount socks and €5 premium socks — and they are noticeable on the foot. SOKKS: 200 needles, flat seams, Oeko-Tex Standard 100, 6-month guarantee. 4 pairs from €19.90.

No — the biggest difference lies in knitting density (100-200 needles), seam processing (overlock vs. flat seam) and quality control. Premium socks go through more production steps than discount products.
200 needles on the circular knitting machine create a stitch pattern twice as dense as 100 needles. Result: Softer feel, higher abrasion resistance and finer appearance.
The toe seam is the only place where the knitted sock tube is closed. Overlock seams create a raised ridge that rubs during extended wear. Flat seams lie flat and cause no pressure points.
