Why Grubs ?


The Foster Family have been making footware since 1776, Grubs is the result of investment into the most advanced materials and technology on our misson to create the most comfortable footware available in the field.

Grubs Ceramic Black Safety Boot outdoor on leaves and mud

All our boots are made to the highest quality standards to meet our exacting requirements. This is nothing new as eight generations of our family have been crafting the finest sports footwear since 1776. Joe Foster, my Great Grandfather, was a founding member of AAA, hand making shoes for the Olympic stars of 1924; Harold Abrams

and Eric Liddell, featured in 'Chariots of Fire'.


My Father and Uncle founded Reebok in 1960 and I was part of the team that created iconic aerobic and fitness shoes that the company is renowned for.

My wife Jan and I created the neoprene revolution in sports and agricultural boots back in 2000. At Grubs our tradition guides us to provide you with the most comfortable performance footwear available today.

"We sell comfort, whatever the weather.

Our boots are the most comfortable you will wear."

- David Foster

Grub's  Technology:

We develop all Grubs boots based on four attributes, these are in order: Comfort, Warmth, Waterproof and Grip. All Grubs boots have these unique properties, making them superior products!

Comfort -

  • Stretch boot shaft made from 5mm INSUFOAM-ULTRA™ allows the boot to fit almost any calf.

  • 6mm NITROCELL™ footbed provides soft underfoot cushioning for an athletic shoe feel.

  • HEXZORB™ technology absorbs heel strike shock for day long comfort.

  • SUPERDRI™ lining wicks moisture away from the wearer's foot to prevent a sweaty and uncomfortable feel. It is fungus and rot proof so will not smell like cotton lined boots.

Warm -

  • 6mm NITROCELL™ footbed has a million microscopic nitrogen bubbles that insulate the wearer from cold surfaces.

  • 5.0 Technology: the full bootie lining wraps the entire foot in 5mm INSUFOAM-ULTRA™ for a comfort range of -20°c to +30°c

  • 8.5 Technology: the full bootie lining wraps the entire foot in 8.5mm INSUFOAM-ULTRA™ with the addition of our 3mm HIGHLOFT™ space insulation for a comfort range of -40°c to +15°c
