Grubs Frostline Boots
Frostline is the best-selling boot in the Grubs welly product range. It is a comfortable everyday boot with excellent grip and thermal insulation, perfect for dog walking, which is one reason it's so popular.
Available online and at our Calverton showroom, as a we have Frostline boots in a wide range of sizes and colours including black, green, purple, pink, and more to suit both men and women alike. The boot upper is a composite material that has an external nylon water-shedding skin bonded to 5mm insulating neoprene. Combined with the rubber boot shell, the whole wellie is fully waterproof. The inner lining is a moisture wicking material, spreading warmth around the boot for added comfort. This level of insulation provides thermal comfort down to -20 Celsius whilst walking.
From a practical point of view, the exposed nylon bonded neoprene upper provides three distinct benefits. First, the boot is lighter than all-rubber wellies. Secondly, without the restriction of outer rubber, the bonded material can expand up to 50 percent to accommodate wider calfs or thicker winter trousers. Finally, the upper can also be rolled down over the lower rubber shell making it easy to tuck trousers within the boot before rolling it back up over the trousers.
Frostline wellies have a TRAX sole manufactured from Duraprene rubber with a Hexorb shock absorbing heel for reduced impact pressure. The sole design includes grip zones at the front and rear of the sole, open central lugs for increased traction, and a prominent heel for downhill braking. The inner sole consists of a 6mm Nitrocell footbed, which is a foam material with nitrogen bubbles. This provides both cushioning and a thermal barrier from the outer sole.
