Based on the Grubs Rainline, the new Grubs Highline follows the same principle of offering a full rubber shafted boot, but incorporating an adjustable clasp to the upper boot to ensure a good fit to most calf sizes. This adjustment being necessary as the full rubber shaft will not expand the same as the full Neoprene upper boots that form the basis of most Grubs Boots The rubber upper is matched with the TRAK outsole with it’s distinctive tractor like tread pattern that provides excellent grip in mud or snow. It also has a prominent heel to provide good braking characteristics. The heel also incorporates a HEXZORB insert. This cushions the impact to the heel when walking. As with all Grubs Boots, the Highline incorporates insulation in the footbed which adds to the cushioning feature of the Hexzorb insert to provide a boot with a comfort range between 70 to -5 Fahrenheit The Grubs Highline will be perfect for Dog Walking and general use on most ground conditions.

Grubs 5.0 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.

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 70 ° to -5 ° Fahrenheit
