John Bull Footwear Size Guide
John Bull offers a range of unisex styles and sizing based on a UK sizing comparison (not a US sizing comparison). If comparing a US size deduct one size as a general guide. For women’s sizing, it is suggested to deduct three sizes from your usual UK women’s size to find your John Bull size. For example if you normally wear a women’s size 7, a John Bull unisex style in size 4 should fit. See the size conversion chart to assist with finding your John Bull size.You can also use the handy foot measure to check your size. Please download the foot measure chart and follow the instructions.

STEEL TOE CAPSafety footwear has a protective toe cap for an important reason—to provide adequate protection against injury. Our steel toe caps are a broad fitting 200 joule impact resistant Type 1 steel toe cap. Steel is the safest toe cap material available, providing the highest levels of resistance in constructed footwear against rolling side compression and cut resistance. 300°C RESISTANTThe outsole is heat resistant to temperatures up to at least 300°C. The material has a very high insulating value and can be expected to provide short term resistance to melting and cracks in temperatures in the highest ranges that will normally be encountered in an industrial environment. PENETRATION RESISTANTProvides maximum resistance against perforation of the sole by nails and other sharp objects. Our boots with this feature have a composite penetration insole. OIL/ACID RESISTANTThe outsole material is resistant to most chemicals encountered in industrial situations underfoot. ORGANIC FAT/OIL RESISTANTThe outsole material is resistant to most organic fats and oils, ideal for kitchen, poultry and farming environments where exposure to biological contamination is a possibility. SLIP RESISTANTThe outsole is compliant to slip resistance to standards in AS 2210.3:2019 and provides slip resistance through a combination of design, tread pattern and material. COOLMAX® LININGCoolmax® Lining fabric helps move perspiration away from the body to the fabric’s outer surface, where it can evaporate quickly. This thermoregulatory effect helps your foot stay dry and comfortable all day. This is included in the Highlander, Jaguar, Oryx, & Crow styles. WATER RESISTANT LEATHERPremium leather is treated to provide extra water-resistant properties. Footwear with this feature is particularly suitable for muddy conditions. CUSHIONCORE®Revolutionary world-first CushionCore 3.0 comfort technology combines two compounds of PU injected into the midsole providing superior shock absorption at the heel while also providing rebound at the forefront as you step. QUAD-MAX FOOTBEDSuper cushioning Comf2Bull Quad-Max footbed of a soft PU with a cushioning heel that’s also antibacterial and washable. WIDE FITWe use our Comf2bull PU footbed with gel insert pads in the heel and forepart for superior shock absorption. The footbed is washable, anti-bacterial and has a breathe easy airflow system. ZIP SIDEFor additional convenience and to help stop water, dust and mud entering the boots. KEVLAR STITCHINGWater-resistant non-wicking stitching ANTISTATICMinimises the amount of static electricity build-up on your body.
