Hiking shoes/boots engineered with GORE-TEX® SURROUND TM product technology are designed for outdoor use in moderate to warmer conditions. They offer enduring waterproof protection and optimum breathability all around the foot. Moisture and warmth also escape through the GORE-TEX® membrane into the open structure of the "spacer" -and from there out of the shoe via side ventilation outlets. The result is faster sweat removal rate. Keeping your feet dry and comfortable even at higher temperatures.
