Cryotuff Boots

Foodmax Boots

Foodmax is a lightweight safety boot that provides superior comfort, is resistant to the chemicals used in the food processing industry and maintains its flexibility in temperatures as low as -40°C. The boot utilises our Cryotuff compound and includes a blown mid-sole which reduces weight and improves cushioning, a cut and abrasion resistant shaft and a vulcanised rubber sole for superior cut and slip resistance.

Chemical Protection
Chemical Protection: EN 13832-3:2006 approval for footwear highly resistant to chemicals.
S4 Category Safety Boot
S4 Category Safety Boot: Complies with the requirements for safety footwear in EN ISO 20345:2011 and additionally includes a closed set region, antistatic properties energy absorption of seat region and resistance to fuel oil.
Slip Resistant SRC
Slip Resistant SRC: Tested and approved for resistance to slip on a ceramic tile floor coated with a dilute soap solution of sodium lauryl sulphate (NaLS) [SRA] and Slip resistance on steel floor with glycerol [SRB]. The tests measure forward slip on the heel and with the boot flat to the floor. Boot Marking: SRC
Vulcanised Rubber Sole
Vulcanised Rubber Sole Description
Energy Absorbing Heel
Energy Absorbing Heel: Provides a minimum of 20J cushioning at the heel, reducing the risk of fatigue and injury to joints and spine. Boot Marking: E
Cut Resistant
Cut Resistant: Resistance to repeated cutting strokes from a sharpened blade (to the method defined in EN 388). Achieves a result of class 4 (minimum pass is 2.5). Boot Marking: CR
Toecap
Toecap: Epoxy coated steel toecap fitted tested for 200J impact resistance and 15kN compression.
Fuel Oil Resistant
Fuel and Oil Resistant: The outer sole is resistant to oil, ensuring the working life of the boot won’t be compromised if used in oily environments. The test involves immersion in oil for 22 hours after which the sole is checked for excessive swelling, shrinkage or increased hardness. Boot Marking: FO
Cold Insulation
Cold Insulation: The thermal insulation properties of the boot ensure that the temperature decrease inside a boot at 23°C when placed in a cold chamber at -17°C is less than 10°C after 30 minutes when measured at the upper surface of the insole. Boot Marking: CI
Hot Contact
Hot Contact: The sole has been tested for contact with a hot metal surface at 300°C for 60 seconds. Boot Marking: HRO
