Shoe Covers Compared: PE vs CPE vs Non-Woven, Anti-Skid, and When to Use Each

A shoe cover is a single-use overshoe pulled over footwear to keep dirt, dust and fluids from being tracked across a clean floor, and to keep the floor’s contamination off the wearer’s shoes. There are three main types. PE and CPE film covers are waterproof but do not breathe. PP non-woven covers breathe but resist fluid less. Anti-skid covers add a heavier fabric or a coated sole for grip. For splash-heavy work, knee-high boot covers protect the lower leg as well. Our shoe and boot covers come in each of these constructions.

Pick the wrong one and you either have staff sliding on a polished corridor or a ward floor wet with fluid soaking through to their socks.

What is a shoe cover, and how is it regulated?

In a hospital, a shoe cover is a medical device, though a simple one. The US FDA’s surgical apparel regulation, 21 CFR 878.4040, lists “operating room shoes and shoe covers” among its examples and places surgical apparel other than gowns and masks in Class I, the lowest-risk class. Outside healthcare, the same product is just protective clothing: worn at cleanroom airlocks, on factory floors, during property viewings and on home service visits.

Whatever the setting, the routine is the same. Put the cover on at the threshold of the clean area, take it off on the way out, and bin it there. A shoe cover worn from the car park to the ward does nothing useful.

PE vs CPE vs non-woven: what is the difference?

The material decides almost everything about how a cover behaves.

Type	Material	Fluid	Breathability	Grip	Best for
PE or CPE film	Polyethylene film	Waterproof	None	Depends on the floor	Wards, labs, wet or dirty floors, visitors, short visits
PP non-woven	Polypropylene spunbond	Resists light splashes only	Good	Depends on the floor	Dry clean areas, cleanrooms, long wear
PP with coated sole	PP non-woven upper, film-coated sole	Waterproof underfoot	Good on top	Non-slip sole	Mixed use: comfort on top, protection underfoot
Anti-skid PP	Heavier PP non-woven (35–40 g)	Moderate	Good	Anti-slip	Smooth or polished floors, factories, repeated walking
Boot cover	Microporous film or PP + PE laminate, knee-high	Fluid-resistant	Some (microporous)	Varies	Theatres, labs, hose-down cleaning, splash-heavy work

PE and CPE. Both are polyethylene film, which is why both are waterproof and neither breathes. The letters are less useful than the numbers: compare weight per piece and size. Our CPE covers weigh 1.8–4.5 g each, come clear or blue in 15 × 35 cm (or to order), and are packed 100 per bag.

PP non-woven. A spunbond polypropylene cover lets air and moisture vapour through, so it is the comfortable choice for staff who wear covers for hours. It resists light splashes but is not waterproof. The fabric is explained in our guide to SMS, spunbond PP and GSM.

Hybrids. Our PP cover with a CPE-coated sole (16 × 42 cm, 5 g) keeps the breathable top and adds a waterproof, non-slip sole, which suits areas where the floor is damp but the shoe is not being splashed.

Do shoe covers prevent infection?

Not in the way many people assume. The CDC’s 1999 guideline on preventing surgical site infection was blunt: “The use of shoe covers has never been shown to decrease SSI risk or to decrease bacteria counts on the operating room floor.” It recommended that staff not wear shoe covers for the purpose of preventing surgical site infection. (CDC has since superseded that guideline with a 2017 update.)

The same guideline gives the real reason to wear them: shoe covers “may, however, protect surgical team members from exposure to blood and other body fluids.” So a shoe cover is protective clothing for the wearer and a floor-cleanliness tool for the facility, not a way to sterilise a corridor.

That has a buying consequence. If the goal is staff protection from fluids, choose for fluid resistance (film, coated sole or boot cover). If the goal is keeping outdoor dirt off a clean floor, a light PP or CPE cover is enough.

When are shoe covers required?

Three sets of rules come up most often.

Bloodborne pathogen exposure. In the US, OSHA’s bloodborne pathogens standard says “surgical caps or hoods and/or shoe covers or boots shall be worn in instances when gross contamination can reasonably be anticipated (e.g., autopsies, orthopaedic surgery).” OSHA is a US rule, but it is a useful benchmark for hospital occupational health policies in the GCC, and knee-high boot covers fit that level of exposure.

Pharmaceutical cleanrooms. EU GMP Annex 1 (2022) sets footwear by grade. In Grade D and Grade C areas, “appropriately disinfected shoes or overshoes should be worn.” In Grade B, “appropriate sterilised footwear (e.g. over-boots) should be worn,” with trouser legs tucked inside. Confirm sterility with the supplier before ordering any cover for Grade B use.

Facility policy. Clinics, laboratories, dental practices, food plants and sites with finished flooring often require covers by house rule rather than law. Light CPE or PP covers are usually enough there.

What does anti-skid mean, and when do you need it?

Here is the problem in one line: a shoe cover sits between the shoe’s tread and the floor, so whatever grip the shoe had, the cover now decides. NIOSH’s guidance on preventing slips in healthcare recommends slip-resistant shoes for staff. A smooth cover over a slip-resistant shoe can undo that.

Anti-skid covers address it in two ways. One is a heavier non-woven: our non-skid PP covers weigh 35 or 40 g, much more than a film cover, and are built for repeated walking on smooth floors. The other is a coated non-slip sole on a lighter cover. Choose anti-skid for polished hospital corridors, factory floors, wet-process areas and anywhere staff wear covers for a full shift. If your safety policy calls for slip-test data, ask for it with the quote.

Which shoe cover should you use where?

Setting	Recommended cover	Why
Wards and visitor entrances	CPE film or PP non-woven	Low cost, quick to put on, keeps outdoor dirt out
Operating theatre support, wet procedures	CPE film, or boot covers for heavy splash	Fluid protection for staff
Autopsy, orthopaedic or other gross-contamination work	Knee-high boot covers	OSHA’s examples of anticipated gross contamination
Laboratories	PP non-woven or CPE	Breathable for long wear, or waterproof for wet benches
Pharma cleanrooms, Grade C and D	Low-lint PP overshoes or boot covers	Annex 1 calls for disinfected shoes or overshoes
Factories and polished floors	Anti-skid PP	Grip on smooth or oily surfaces
Property viewings and home service visits	CPE or PP	Protects finished floors, quick on and off

How do you work out quantities?

Every entry uses a pair. A clinic with 50 visitors a day uses 100 covers a day before counting staff, which is about one bag at 100 pieces per bag, or roughly 20 to 26 bags a month depending on opening days. CPE covers come 20 bags to a carton and PP covers with a coated sole 10 bags to a carton, so a carton of CPE covers lasts that clinic around three weeks.
