Grubs Adventure Boot

Built with comfort in mind, the Grubs Adventure boot is made for fitness and general walking in cold weather. A relaxed  4mm insu-foam-ultra bootie is lined with superdri shearling lining for warm and comfortable insulated performance down to -20 degrees. Rubber toe guard and reinforced counter protect and support the foot throughout the range of walking activities and the branded power-band holds the foot into the heel of the boot. The boot shaft can be turned down to alter the amount of leg coverage and to ventilate the boot when in use. Waterproof Warmth Comfort Grip.

All Grubs footwear uses self-insulating INSU-FOAM ULTRA bootie construction which acts as a neutral medium between the wearer and the outside.

This unique super stretch material is commonly used in deep sea dry suits, and  has a 300% stretch rating. It is then covered with a 4 way stretch knitted nylon jersey which as suggested can expand not only in width but also height.
