Grubs Gummistiefel Frostline Unisex Classic Wellies Green

Most GRUBS® Rubber footwear uses self-insulating INSU-FOAM ULTRA™bootie construction which acts as a neutral medium between the wearer and the outside. The bootie is both waterproof and insulating and exceeds the long-term effectiveness of waterproof membranes and lofted insulations. The boots are waterproof to EN ISO 20344: 2004 5.7 standard. FROSTLINE 5.0™ is insulated and waterproof, with excellent grip, made for all day comfort.

5MM INSU-FOAM ULTRA™ - gives all round foot comfort and insulation.

6mm NITROCELL™ footbed - provides a soft cushioning for an athletic shoe feel. A million microscopic nitrogen bubbles that insulate the wearer from cold surfaces.

UNDERFOOT CHASSIS™ - give a sure footed platform.

HEXZORB™technology - absorbs heel strike shock for daylong comfort.

SUPERDRI™ lining - is hard wearing, wicks moister 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.

TRAX™ outsole - superior grip on a variety of surfaces, the tread is designed to work with the action of the foot

COMFORT RATING - -20 Degrees Celsius to +20 Degrees Celsius

We recommend purchasing the same UK size as your regular daily footwear, such as a trainer. Grubs Boots have a 15mm allowance for a woolblend / thicker sock which also means if you are a half size, we recommend sizing down.
