These Grubs Frostline Boots are the ultimate footwear in both comfort and grip. A high performance, field boot constructed with Insu-Foam technology which is super soft and because of its microcellular structure, stops heat from escaping out allowing you to stay dry and comfortable for longer.

These Frostline boots are designed using the latest technology and are finished off with a 2mm tough natural rubber outer layer for superb protection from the undergrowth. These boots are designed to stretch 100% in the uppers so they can offer you a perfect fit around the calves as well as keeping your feet very warm.
