We Don't Just Offer Plus Sizes—We Build Your Size System
The biggest hidden cost in plus size compression is sizing chaos: no universal standard, every brand's chart different, returns driven by mis-fits. We define the size architecture with you before we knit a single pair.
What we define together:
- Foot length ranges
- Ankle circumference
- Calf circumference bands
- Calf height (knee-high length: petite / regular / tall)
- Thigh circumference (for thigh-high styles)
- US / EU / UK size chart adaptation
- Size naming aligned to your market (2XL–6XL or your own system)
- Packaging size guide & product insert artwork support
Why Plus Size Compression Can't Just Be "Bigger"
Size-Matched Knitting
Each circumference band runs on the correct cylinder needle count with high-recovery elastane plating; pre-production samples are confirmed before bulk.
In-House Pressure Testing
Compression is verified in-house on our Swisslastic MST MK V. During development, representative or boundary sizes are checked against the target pressure profile; production testing scope is defined according to the approved specification, size range and buyer requirements.
Measurement-Led Grading
Calf, ankle, foot length and leg height are graded around the target wearer rather than scaled by one rule. A sock that only widens at the calf fails at the instep — and a sock that scales everything together leaves the footbed too large.
Wide Comfort-Top Cuff, No Dig-In
Widened rib cuff distributes top-band pressure; stay-up via anti-slip yarn (silicone band reserved as medical-grade option).
Engineered to Your Exact Specifications
Custom Colors
Pantone-matched dyeing; plus sizes run the full pattern range, same as standard sizes.
Custom Logos
Knitted-in or printed logo placement engineered not to distort on wide calves.
Material Selection
Softer hand feel: combed cotton or bamboo. Higher abrasion resistance and faster drying: nylon-led blends and Coolmax. Temperature regulation: merino. Antimicrobial finishes optional. Compare the full yarn range →
Compression Level
15–20 / 20–30 / 30–40 mmHg, available across the full size range.
Custom Packaging
Retail-ready boxes, blister packs, and fully custom size-guide inserts.
Stay-Up System
Wide rib cuff standard; anti-slip yarn or medical silicone band options available.
Quality Control Built Around Pressure Accuracy
In extended sizes, the real risk is that a larger sock stops behaving like the approved sample. Our four-stage QC is built around carrying the approved specification from sample into bulk.
Yarn & Material Inspection
Every elastane and yarn batch is inspected on arrival for elasticity and recovery consistency—the foundation of stable compression at larger circumferences.
In-Line Knitting Checks
During production, flat-width and circumference are checked against each size band's spec sheet, so a 3XL is knitted as a 3XL—not labeled as one.
In-House Pressure Testing
Swisslastic MST MK V — medical-grade compression testing in-house
Compression is verified against the approved specification to confirm the graduated profile holds from ankle to calf. Testing scope and reporting are defined according to the specification, size range and buyer requirements.
Final AQL 2.5 Inspection
Pre-shipment random inspection to AQL 2.5 covers sizing, stitching, cuff integrity and packaging before your order leaves the factory.
