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.
In our 5.0 TECHNOLOGY™ boots the bootie is lined with moisture wicking terry knit, which keeps the wearer dry and has a super stretch to fit most calves. As INSU-FOAM ULTRA™ is a temperature neutral material it will keep the wearers foot comfortable in most conditions for a prolonged period.
TEMPERATURE RANGE 85 to -5 Fahrenheit
