Frostline Womens Classic Wellies

Frostline 5.0™ is insulated and waterproof, with excellent grip, made for all day comfort. 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. • 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 wool blend / thicker sock which also means if you are a half size, we recommend sizing down.
