Footwear is a high-frequency contamination vector: floors collect particles and residues, then shoes transfer them to traffic lanes, gowning areas, and controlled spaces. Shoe covers are a straightforward control intended to reduce what is carried in on shoes and to add a barrier layer during wet maintenance or liquid handling work. The best shoe cover in the world will still underperform if gowning flow, donning technique, and entry discipline are weak—so this entry includes donning guidance alongside product attributes.

• Reducing particulate carry-in from shoes at controlled entry points and change areas.
• Adding a liquid/particle barrier layer during washdown, pressure washing, and wet maintenance activities.
• General industrial contamination control where a microporous barrier is preferred over lightweight visitor covers.
• Supporting traffic control programs (tacky mats, defined lanes, routine wipe-downs) to reduce recontamination.

• Barrier-focused laminate: microporous film laminate construction is published for A40 accessories.
• Footwear coverage features: elastic opening and seamless-sole format supports practical on-shoe coverage.
• ESD/antistatic relevance: static decay performance is published as a pass to NFPA 99 criteria for A40 accessories.
• Operational throughput: 300/case supports high usage rates at entry points and maintenance staging areas.
• Program consistency: published test methods and results help QA teams compare options on more than “feel” and price.

Manufacturer literature describes A40 accessories as a microporous film laminate platform. For the shoe cover (27000), the published product attributes include elastic opening, 7" height, a seamless sole, and universal sizing.

Shoe covers are intended to be worn over standard footwear. Fit, coverage, and donning behavior matter as much as fabric performance—especially at the ankle and sole edges where gaps and snagging can occur. If your SOP requires higher overlap with coveralls or leggings, consider an ankle-high or overboot format.

The table below consolidates key attributes for receiving, SOP alignment, and practical use. Where the manufacturer literature provides test results at the platform/accessory level, those are listed as “published (A40 accessories).”

Attribute	27000 (A40 Shoe Covers)
SKU / Code	27000
Material platform	Microporous film laminate
Sizing	Universal / one size fits all
Height	7" (published)
Sole	Seamless sole / no bottom seam
Opening	Elastic opening / elastic top
Seams (published for A40 accessories)	Serged seams
Color	White
Case pack	300 per case (3 bags of 100)
Antistatic (published for A40 accessories)	NFPA 99 static decay pass (<0.5 sec)
Country of origin	Not stated in the manufacturer source basis listed below

For shoe covers, “performance” typically means: barrier behavior (liquid splash resistance, particle holdout), low-lint suitability for the environment, and practical durability during walking. Manufacturer literature for A40 accessories publishes test methods and results at the platform/accessory level; use those values as comparative inputs and qualify for your specific floor chemistry, abrasion, and SOP use time.

Characteristic	What it means for use	Published basis (A40 accessories)
Hydrohead	Indicator of resistance to water penetration (relevant to splash and wet floors).	AATCC 127-1998 result published.
Particle holdout (0.3–0.5 µm)	Useful comparator for barrier behavior against fine particulate challenges.	Independent lab result published (platform/accessory basis).
Lint (particles >0.5 µm)	Helps estimate shedding risk; always validate in your airflow/traffic conditions.	INDA method reference and result published.
Static decay	Relevant where static control and ESD-sensitive environments are considerations.	NFPA 99 pass (<0.5 sec) published.
Chemical / blood penetration references	Useful comparisons for barrier intent; confirm applicability to your hazards and PPE selection.	ASTM methods and pass statements are published for the platform/accessory literature.

Receiving teams should verify: correct SKU (27000), correct case quantity (300), packaging integrity, and any site-required documentation. For programs that require country of origin confirmation or special declarations, treat that as a receiving requirement and request documentation prior to qualification.

The donning “order of operations” is facility-specific. Many programs control the dirtiest-to-cleanest flow (shoe/boot control early, then garments, then gloves), while others require footwear steps to occur at specific bench transitions. Follow your SOP and validate the method using your site’s particle/micro monitoring outcomes.

• Dragging the cover before it is on: handle by the opening and keep the sole off benches/garments.
• Ankle gaps: confirm elastic sits above shoe collar; choose higher coverage options when required.
• Overuse beyond SOP wear time: set change frequency and enforce it (especially after wet-floor exposure).
• Recontamination after donning: avoid stepping off controlled lanes and then re-entering without changing shoe covers.

Closest alternatives are other barrier-focused shoe/overshoe products, including ankle-high shoe covers and overboots used in cleaner or more regulated gowning programs. Compare: coverage height, sole construction, seam design, packaging, and documentation—then validate in your environment.

• Kimtech A7 ankle-high shoe covers: higher coverage option for overlap requirements.
• Kimtech A8 shoe covers: cleanroom-oriented alternative depending on SOP and area classification.
• Overboots / sterilized overshoes: use when your SOP or regulatory framework requires sterilized footwear components.

27000 shoe covers are typically selected for industrial and controlled-entry contamination-control workflows where a breathable barrier laminate is preferred over lightweight visitor covers. If your environment requires sterile footwear components or higher coverage overlap, select products supplied and documented to that requirement and validate the donning method in your program.
