Grub's Ptarmigan Boot
Grub's Ptarmigan Boots use 5mm Insu-Foam-Ultra - a tough four-way stretch nylon face with a water shedding surface finish. 5mm high grade Insu-foam is light, highly insulating and naturally buoyant and features a moisture wicking terry knit lining.
Conceived by the design brain behind some of the world’s greatest footwear successes, Grub's provides the most comfortable, high performance gear for the most discerning wearers.
Grub's footwear is based on a 5mm chloroprene rubber booty, which is lightweight, insulating, flexible, buoyant and resistant to mildew, unlike traditional rubber and leather boots.
The tough texturised nylon face has a durable, water-shedding surface and stretches to fit snugly.
The ankle, foot and toes are protected by the natural rubber shell and a toughened toe cap.
Inside a knit lining wicks moisture away from the wearer and each model has a reflective pull-on loop to the rear.
