Grubs Frostline 5.0 Wellington Boots - Black - Size 12

Forget soggy feet on the job site or in the garden. When you are tackling tough outdoor work in any weather, you need reliable footwear that actually performs. The Grubs Frostline 5.0 Wellington Boots in Black size 12 are built for tradespeople and DIYers who demand practical comfort, safety, and durability without chasing fleeting fashion trends. Engineered to operate in temperatures from -10ºC to 30ºC (85ºF to sub zero!), these knee-length boots keep your feet dry, warm, and stable on rough ground.

Inside and out, smart technology does the hard work. The unique INSU-FOAM ULTRA and 5.0 technology combine a self-insulating micro cellular construction material with a moisture wicking terry knit liner, making each boot super soft and bouncy while repelling water and retaining heat. Designed to stretch and fit calves up to an additional 100% of the wellies' upper calf diameter, they deliver a snug fit that makes all the difference during long shifts outdoors and in.
