The Grubs Penline 5.0 Half Height Boot featuring the TRAX™ sole with Hexzorb™ shock-absorbing technology. This sole has tractor like treads making it great for heavy mud and manure. The TRAX sole is what we call an "easy clean out sole" helping to clean out mud while you walk rather than lugging it around. 

Constructed with Grub's 5.0™ thermal technology, the Penline 5.0 is the perfect boot for the field and the comfort and warmth will allow you to keep competing in all forms of outdoor leisure & sport. Read more about the benefits of insulated boots here.

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.
