Designed for hiking! As the temperature rises the body's metabolic activities also increase. The body has to expend energy simply to regulate its own temperature. And the foot has a particularly hard time regulating its temperature because it's enclosed in a hiking shoe. In an effort to cool itself off the foot constantly produces perspiration. But tightly encased in a shoe this natural cooling process cannot function properly. Despite the fact that today's shoes are made of high-tech materials they can't create the ideal 'barefoot environment' necessary for foot comfort. X-Socks - Extreme are specifically designed to transfer heat and moisture away from the foot and out of the shoe.
These socks really work a few words don't do them justice. They are left and right specific because one of the features is a ventilation channel that starts in the arch and channels air up out of the boot. If you have a few minutes take the time to click the link to the technology guide it explains the features of the socks. Oh and the manufacturers guarantee them for 2 years activiate the guarantee through their website. All for a tenner a pair!
