Microfiber Suede Developed Around Safety Footwear Requirements
Our EN ISO 20345-oriented microfiber suede is intended for safety shoe, safety jogger and work-boot upper development where tear strength, repeated toe flexing, breathability and consistent material construction need to be evaluated together.
The current product uses a dense non-woven microfiber structure with a micro-porous PU matrix and is offered in 1.8 mm and 2.0 mm gauges. Rather than treating EN ISO 20345 as a material certification, we use the footwear program's required test methods to help buyers select and validate the proposed upper material.
Current gauges are positioned for structured safety uppers.
Current page lists this value for material evaluation.
Defined usable width supports footwear cutting plans.
Separate Published Product Data from Report-Verified Results
The current product page lists several mechanical and comfort properties. For procurement approval, each numeric result should be matched to the applicable TDS, internal test record or third-party report for the exact sample, thickness, color and construction.
| Material Construction | Dense non-woven microfiber structure with micro-porous PU matrix |
|---|---|
| Current Gauge | 1.8 mm / 2.0 mm |
| Current Tolerance Claim | ±0.05 mm is published; verify against applicable TDS |
| Usable Width | 137 cm / 54 inches |
| Tear Strength | ≥60 N is currently published; match method and specimen direction to the applicable report |
| Repeated Flexing | >100,000 cycles is currently published; confirm dry/wet condition, method and failure criterion |
| Water Vapor Permeability | ≥0.8 mg/(cm²·h) is currently published; verify method, conditioning and tested construction |
| Chemical Resistance | Do not generalize; specify actual oil, acid, alkali, concentration and exposure requirement |
| REACH | Check the declaration or report against the exact ordered material and applicable substance scope |
| EN ISO 20345 | Finished-footwear standard; material evidence may support selected footwear tests but is not a raw-material certification |
Why the Microfiber Structure Matters Around a Safety Toe
Safety footwear puts concentrated mechanical stress near the vamp, toe-cap transition, eyelet panels and stitched reinforcement zones. The upper therefore needs more than an attractive suede surface.
A dense microfiber base helps create a more engineered and repeatable substrate than a naturally variable hide. For buyers, the practical question is whether the proposed construction holds the required thickness, tear behavior and flex performance through the actual cutting, stitching and lasting process.
- Check material body around rigid toe structures
- Evaluate cut-edge stability on shaped vamp panels
- Review stitch-hole behavior near reinforcements
- Inspect the surface after lasting
- Compare flex-zone appearance after repeated bending
Use the Required EN ISO 20344 Test Method for Each Material Property
Safety-footwear material development should begin with the test requirement, not with a marketing adjective. "Durable," "breathable" and "oil resistant" have little procurement value unless they are tied to a defined method and acceptance limit.
Tear Strength
Confirm specimen direction, preparation, method and required minimum. The current page lists ≥60 N but the applicable report should be reviewed before approval.
Flex Resistance
Define dry or wet conditioning, flexometer method, temperature, cycle count and failure criterion for the upper material.
Water Vapor Permeability
Review the test method and unit together with the complete shoe system. Lining, foam and reinforcement also affect wearer comfort.
Abrasion
State the required Martindale or other abrasion procedure instead of comparing cycle values from different methods.
Peel / Layer Adhesion
Specify specimen width, direction, test speed and acceptance value when coating or laminated-layer integrity is critical.
Hydrolysis / Chemical Exposure
Define temperature, humidity, chemical identity, concentration, duration and final acceptance criteria.
Validate Flexing on the Actual Vamp and Toe-Cap Geometry
The vamp is one of the most mechanically demanding areas of a safety shoe. It repeatedly folds near the toe-cap edge while also carrying seam tension and surface compression.
The current page publishes more than 100,000 flex cycles, but a cycle figure alone does not establish suitability. Buyers should check whether the test method, wet or dry state, temperature and failure endpoint match their footwear specification.
- Test the selected production gauge
- Include the specified dry or wet condition
- Inspect for cracking, delamination and permanent creasing
- Compare flex behavior before and after lasting
- Record the exact failure criterion
Do Not Evaluate Water-Vapor Performance in Isolation
The product page currently lists water-vapor permeability of ≥0.8 mg/(cm²·h). This can be useful as a material-level reference, but the comfort of a safety shoe depends on the entire upper and lining system.
Foam reinforcement, membranes, adhesives, linings and the proportion of microfiber suede used in the upper can all change the moisture behavior of the finished shoe. For long-shift footwear, validate the complete footwear construction rather than relying on one material number.
Where This Microfiber Suede Can Fit Safety Footwear Programs
Safety Joggers
Relevant for athletic-style safety footwear requiring a structured but flexible upper around protective components.
Industrial Safety Shoes
Evaluate tear, flex, breathability and seam behavior according to the finished shoe specification.
Work Boots
Heavier constructions may require additional abrasion, hydrolysis or chemical exposure validation.
Protective Trainers
Thin athletic-style upper designs can benefit from consistent engineered material construction.
OEM Safety Footwear
We can review gauge, surface, color and test requirements around the buyer's actual footwear program.
Approve the Material on the Same Construction Planned for Bulk
Custom color, surface feel and gauge should be evaluated together. Changing thickness, PU formulation, backing or finish after the test sample has been approved can change both processing behavior and physical performance.
We recommend keeping one approved reference that links appearance to the technical specification and test evidence used for the footwear project.
- Confirm 1.8 mm or 2.0 mm target gauge
- Provide physical color or suede reference
- Define nap and surface appearance
- Specify test methods before sampling
- Retain the approved swatch for bulk QC
From Safety Footwear Requirement to Approved Bulk Material
Share safety category, upper zones, construction and target market.
State methods and acceptance limits for the required material data.
Run cutting, stitching, lasting, flex and finished-shoe trials.
Link the approved material sample to TDS, QC and applicable reports.
Match Every Report to the Material Being Purchased
Our public certificate archive includes historical footwear test evidence, but a report for one submitted microfiber suede sample cannot automatically be transferred to a different color, backing, formulation, thickness or production lot.
For a new safety-footwear program, provide the applicable test list. We can review the proposed sample, available documentation and whether new testing is required before bulk approval.
Request Safety Footwear Material Evidence
Send us the footwear application, annual volume, target thickness, usable width, color or surface reference, required EN ISO 20344 test methods, destination market and project schedule. We can review the relevant sample, TDS and available test evidence.

EN ISO 20345 is a finished safety-footwear standard, so raw microfiber suede should not be described as independently EN ISO 20345 certified. Material-level testing can support a footwear program, while final compliance depends on the complete shoe and applicable assessment.
WINIW's public evidence directory currently identifies SGS report SL918192716604FW-01, dated 19 September 2018, for a submitted suede microfiber leather sample with selected tests requested against EN ISO 20345:2011. The sample identity and scope should be checked before using the report for a current order.
The current product page lists ≥60 N tear strength. For procurement approval, the test method, specimen direction, sample construction and applicable report should be checked before treating that figure as a contractual acceptance limit.
These are the two gauges currently listed for this product. Tell us the upper application, footwear design, color and test requirements so the proposed sample can be reviewed before bulk production.
Yes, but provide the exact test method, chemical or aging condition, exposure duration and acceptance criterion. General terms such as "oil resistant" or "hydrolysis resistant" are not sufficient for a B2B material specification.
Please provide footwear type, upper application, annual volume, target thickness and tolerance, usable width, color or surface reference, required EN ISO 20344 test methods, destination market and required production schedule.
