Grubs Boots 8.5 Technology

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.

A moisture wicking polyester fleece lining combined with our HIGHLOFT™ liner is made from thousands of tiny fibers that allow air to circulate and trap heat, like down feathers. the liner wicks away excess perspiration and creates a comfortable temperature inside the boot in bitter winter weather.

TEMPERATURE RANGE 60 to -40 Fahrenheit
