Thermally insulating

Purofort prevents heat loss and provides thermal insulation down to -20°C and even to -50°C. No more cold feet!

Flexible

Purofort is extremely flexible, giving you maximum comfort.

Strong

The Secret Dunlop Recipe

Purofort is a unique material. It has a secret recipe, only known to Dunlop. For each type of Purofort boot, a specific recipe is created in the Dunlop lab. The ingredients depend on the application and the required properties of the boot.

Purofort contains millions of air pockets. Because they are mixed under high pressure, they are evenly distributed. This is quite unique, as Dunlop is the only boots manufacturer in the world that uses high pressure technology to produce its boots. And it's very beneficial for you: thanks to the evenly distributed air pockets, Purofort provides extreme thermal insulation, keeping your feet warm in the coldest conditions. And because air and solid material are optimally mixed, Purofort is lightweight and comfortable.

Purofort is extremely flexible and cut resistant, due to its molecular structure. This structure contains hard and soft blocks. The hard blocks make your boot resistant to cuts and abrasion, giving them a longer lifespan. The soft blocks allow for a thinner shaft which increases flexibility and comfort.

There are custom Purofort® solutions for Agriculture and Fishery, Construction and Industry, Food Processing, Oil, Gas and Mining, and Functional Leisure, each equipped with its own unique product features.

Your boots should give you ultimate protection. This is impacted a lot by the performance of your outsoles. As slipping and tripping occurs mostly during walking when landing on your heel and taking off from your toes, Dunlop pay special attention to these areas.

That's why they design outsoles that exceed your requirements on slip resistance and grip. Dunlop outsoles are additionally dirt repellent and wear resistant, assuring a long life time of your boots.

• OB = Meets the basic requirement of a slip-resistant sole.
• O1 = Slip-resistant sole, closed heel area, an energy absorption heel, and antistatic.
• O2 = Same as O1, plus prevents water penetration.
• O3 = Same as O2, plus midsole penetration resistance and cleated outsole.
• O4 = Same as O1, applied to footwear made with rubber or polymer uppers.
• O5 = Same as O4, plus midsole penetration resistance and cleated outsole.
• O6 = Has all the O2 features, plus permanently waterproof.
• O7 = Has all the O3 features, plus permanently waterproof.

If the above code portion ends with:

• L = non-metal midsole penetration resistance (tested with 4.5mm(dia.) nail)
• S = non-metal midsole penetration resistance (tested with a 3.0mm(dia.) nail)

If the standard includes any of the following letter codes, that means the footwear has those features.

• AN – Ankle Protection
• A – Antistatic properties
• C – Conductive footwear
• I – Electricity insulating footwear
• ESD – Reduces electro-static buildup or discharge to reduce risk of damage to sensitive electronic components and devices.
• CR – Cut Resistant Upper
• M – Metatarsal Protection
• WRU – Water Resistant Upper
• WR – The entire shoe is waterproof
• LG – Ladder grip
• P – Penetration resistance
• CI – Insulation against cold surfaces
• HI – Insulation against hot surfaces
• HRO – Heat Resistant Outsole
• SRA – tested on smooth ceramic tile with dilute soap solution
• SRB – tested on smooth steel with glycerol (mimicking oily or greasy conditions)
• SRC – tested under SRA and SRB conditions
