Grubs Bearline 8.5 Wellington Boots
 
Graded for comfortable wear in temperatures as a low as a  -40ºC, Wellington boots don't get warmer than the Grubs Bearline 8.5 Heavy-Duty Thermal Waterproof Winter Wellinton. They combine thick Duraprene (a higher performance neoprene) and 360° soft insulation to keep your feet warm and dry no matter the weather.
Featuring bouncy and supportive soles, they reduce foot fatigue and absorb shock, while the roughened BEARPAW soles are extremely anti-slip in wet and icy conditions.
