S5 Safety Boots: Features, Differences and Use cases

S5 safety boots are footwear used in places with constant water or liquids. They are suitable for wet or humid environments. S5 rating is a safety class specifically for all-rubber or all-polymeric footwear. Aside from having the same features as S4 Safety shoes, this class has two benefits: midsole penetration resistance and cleated outsole.

They are water and leakproof, making them ideal for weather or work. S5 safety footwear meets the basic safety footwear requirements of EN ISO 20345. They provide high-level protection and comfort to the wearer. They protect against risks like falling objects, crushing and treading on sharp objects such as nails or screws, slips, and water penetration.

Features of S5 Safety Boots

  • Total waterproof protection
  • Protective toe cap
  • Midsole penetration resistant
  • Cleated outsole
  • SRC
  • Anti-static properties 
  • Puncture Resistant Soles
  • Oil and petrol resistant 

Water Proof Protection 

S5 safety boots are designed to ensure you do not come into contact with liquids at the workplace. They are designed with rubber or polymeric materials suitable for wet environments. It keeps your feet dry, warm, and comfortable.

Protective Steel Toe Cap

All S5 safety boots usually have a steel toe cap responsible for protecting the feet against impact hazards up to 200 joules in strength. Steel Toe Caps are more naturally more rugged than composite toe caps. They conduct cold, heat, and electricity. At the workplace, the steel toecap generally protects your toes against sudden impact with an object.

Midsole Penetration Resistance

This is an additional unique feature of S5 safety boots. They have a composite or steel midsole that protects against upward penetration. The Anti Perforation midsole protects the feet against penetrations through the boot sole as they are usually impenetrable. Most S5 midsoles are usually by EN ISO 20345:2011.

Cleated Outsole

S5 safety boots are usually equipped with cleats that furnish a grip. They are slip-resistant. The outer sole gives a good grip and is SR-certified (SRA, SRB, and SRC). They are resistant to wet ceramic and steel floors with diluted soap solution and glycerol.


S5 Safety boots have anti-slip properties, which give you a firm stance. Slip Resistant Soles are one of the major elements in safety footwear. SRC slip-resistant soles have passed both SRA and SRB slip-resistant tests, which are usually tested on steel and ceramic surfaces.

Anti-Static Properties 

Static discharges have the potential to set combustible mixtures ablaze and cause damage to electronic components. When you come into contact with the ground while wearing S5 Safety boots, static electrical charges are transferred to the ground. It does this by lowering the amount of static electricity that builds up in the body.

Puncture Resistant Soles

The S5 safety shoes are designed to work in environments with high humidity and the presence of oils or hydrocarbons. S5 boots generally protect against perforation risks of the sole. The soles of the boots protect your feet against injury, which may occur as a result of sharp objects penetrating the soles.

Oil and Fuel Resistant 

The S5 Safety Boots’ soles have undergone testing and be resistant to oil and fuel.

What is the Difference Between S5 and other Safety Shoes

The following unique features differentiate S5 and other safety classes.

  • S5 Safety boots: Leak-proof with midsole and can resist penetration.
  • S4: Leak-proof 
  • S3: Midsole Penetration Resistance 
  • S2: Prevents water penetration 
  • S1: Anti-static, Oil-Resistant, and Energy Absorption

Industries that wear S5 Safety Boots

There are so many industries for which the S5 safety boots are not ideal. A lawyer wouldn’t wear safety boots to work as there are not so many hazards in his/her/working environment. The S5 safety boots are ideal for the following industries:

  • Food Processing
  • Agriculture 
  • Gardening
  • Petrochemical
  • Construction
  • Light/Electrical
  • Heavy Industry 
  • Cleaning Industry
  • Forestry

They are also resistant to common disinfection agents, oil, and fats, which gives the boots long-lasting benefits.


The anti-clogging vulcanized rubber sole of the S5 safety boot provides the highest level of slip resistance possible, even in conditions where there is a lot of mud. They make wearing them in any weather more bearable for the person doing so.


The Anti Perforation midsole protects the feet against penetrations through the boot sole as they are usually impenetrable. This makes it ideal for gardeners. The boots provide ultimate comfort to the user. The steel toe cap protects the toes against falling objects in the garden. 


Individuals or workers can easily protect their feet from various hazardous chemicals in the workplace with S5 Safety Boots. These shoes are ideal for workers in this industry due to their anti-static properties, integral steel toe caps, and vulcanized rubber soles, all of which provide slip resistance.


Workers in the construction industry require protection against hazards such as falling objects, being crushed, and inadvertently treading on sharp objects like screws and nails. Because of this, S5 safety boots are an excellent choice.

They allow the wearer to remain comfortable throughout the day, regardless of the temperature or the weather.


There are some dielectric S5 safety boots available. They are utilized in settings where there is a high probability of receiving electric shocks due to the presence of high voltages. They guard the material’s insulating properties and prevent electrical current from reaching the ground.

Heavy Industry 

S5 safety boots are suitable for heavy industries such as mines. They offer protection and comfort to the wearer. The steel toe cap protects the toes from falling objects, and the midsole penetration resistance protects the feet against external object penetration. 

Cleaning Industry 

S5 safety boots are ideal for cleaning workers as they are usually slip-resistant, giving a firm grip and stance. They are also ideal for environments with liquids or moisture. They keep the feet warm and provide maximum comfort all day long to the wearer.


S5 safety boots are ideal for Forestry activities. They protect the feet against heavy falling objects. They also protect against different forms of chemicals used. The S5 safety boots, with their anti-clogging vulcanized rubber sole, provides ultimate slip resistance in wet or muddy conditions. They give maximum comfort and balance to the wearer all day long.


What Cases should S5 Safety Boots be used in?

If you need boots that have toecaps that are puncture-proof plates, you should strongly consider buying a pair of S5 safety boots. They provide complete comfort and the highest possible level of protection in the event of an accident.

In situations such as these, you should use the:

  • Conditions where there is a high humidity level: They should be worn in conditions with a significant amount of liquid present. They are impervious to water.
