At WIDEWAY GROUP (Jinjiang Wanwei Import & Export Co., Ltd.), quality is not an afterthought—it is systematically calibrated into every pair of shoes before production begins. Located in ChenDai Town, Jinjiang City—China's Footwear Capital—our dedicated testing laboratory operates alongside the provincial National Footwear Testing and Inspection Center (福建省鞋类产品质量监督检验中心).
Every batch of athletic sneakers, lifestyle trainers, casual shoes, and recovery slides undergoes rigorous physical testing conforming to international standards including SATRA TM55, ISO 20344, ASTM F2413, and EN ISO 17708. From cold-flex endurance at -10°C to high-temperature UV solar aging, we ensure your footwear performs under extreme climate conditions across North America, Europe, and worldwide retail markets.
Independent QA inspectors monitor every workstation across raw material delivery, CNC cutting, automated stitching, lasting assembly, and container loading.
Every batch of incoming Flyknit mesh, TPU sheets, action leather, EVA pellets, and rubber soles undergoes rigorous bench testing before warehouse release:
Multi-ply oscillating knife cutting beds cut shoe components with CAD digital nesting accuracy:
Uppers stitched on CNC automated pattern machines and post-bed machines inspected in-line:
Computerized hydraulic lasting and conveyor assembly line strictly governed by temperature and pressure curves:
Every finished shoe must clear complete cosmetic cleaning and electromagnetic security screening:
Independent QA team or buyer third-party inspectors (SGS, BV, Intertek, QIMA) conduct random audits:
| Test Parameter | International Standard | WIDEWAY Benchmark Target | Laboratory Test Equipment | Quality Purpose |
|---|---|---|---|---|
| Bally Upper Flex Resistance | SATRA TM55 / ISO 5423 | ≥ 100,000 cycles (23°C) / 50,000 cycles (-10°C) | Multi-Station Bally Flexometer | Ensures uppers do not crack, peel, or wrinkle under continuous running gait. |
| Sole Bond Adhesion (Peel Test) | SATRA TM411 / EN ISO 17708 | ≥ 3.5 N/mm (Material tear before bond breaks) | Computerized Electronic Tensile Tester | Guarantees zero sole separation between outsole, midsole, and upper during sports wear. |
| Outsole DIN Abrasion Resistance | ISO 4649 / SATRA TM174 | Volume loss ≤ 130 mm³ (Rubber) / ≤ 180 mm³ (EVA) | DIN Rotary Drum Abrasion Tester | Maximizes outsole wear life across asphalt, outdoor trails, and indoor sports gym floors. |
| Martindale Lining Abrasion | ISO 12947-2 / SATRA TM31 | 25,600 rubs dry / 12,800 rubs wet (No yarn breakage) | 4-Head Martindale Wear Tester | Prevents collar mesh and footbed lining from wearing holes or causing friction blisters. |
| Ross Outsole Flex Fatigue | ASTM D1052 / SATRA TM60 | 50,000 flexes at 60° angle, cut growth ≤ 4.0 mm | Ross Flexing Test Apparatus | Simulates continuous toe bending; certifies rubber/EVA compounds against flex rupture. |
| Anti-Yellowing UV Solar Resistance | HG/T 3689 / ASTM D1148 | ≥ Grade 4.0 on Grey Scale (after 48h UV exposure) | Accelerated UV Aging Chamber (300W Lamp) | Crucial for pristine white sneakers, EVA midsoles, and transparent icy rubber outsoles. |
| Electromagnetic Needle Detection | Apparel Safety / CPSC / CE | 100% pass detection of 0.8 mm Ferrous (Fe) sphere | Dual-Head Conveyor Needle Detector Tunnel | Zero broken sewing needles or metal debris entering finished footwear cartons. |
| Eyelet & Hook Pull-Out Strength | SATRA TM149 / ISO 17706 | ≥ 180 N (No eyelet displacement or upper tear) | Digital Eyelet Fastener Pull Tester | Ensures heavy-duty lacing durability for trail runners and high-stress outdoor boots. |
In collaboration with international testing laboratories SGS and Intertek, all raw materials used across WIDEWAY manufacturing lines are pre-screened against the Restricted Substances List (RSL). We guarantee 100% non-toxic products conforming to European, American, and Japanese safety regulations.
Need physical test data sheets or SGS/Intertek chemical test certificates for your customs clearance or retailer compliance?
Download Lab Report SampleChenDai Town in Jinjiang City is internationally renowned as the world's most concentrated footwear supply chain cluster. Within a 15-minute radius of WIDEWAY's facility, over 3,000 specialized material suppliers, outsole mold tooling workshops, and official municipal testing institutes operate symbiotically.
If any physical test or color fastness parameter deviates during incoming material inspection, replacement compound batches and re-engineered Flyknit yarns can be delivered and re-tested within 4 to 8 hours. This hyper-dense industrial proximity eliminates weeks of transit delay experienced by isolated overseas factories.
We welcome third-party audit firms (SGS, Intertek, Bureau Veritas, QIMA) and brand QC representatives to inspect our lines and laboratory in Jinjiang.
