Running is one activity that requires the use of waterproof socks like SealSkinz. During this strenuous physical activity, the feet perspire and become uncomfortably hot. While you may think that waterproof socks only protect your feet from water getting to your feet, the socks also allow the feet to breathe and eliminate moisture from the inside as well. This makes running and other strenuous activity more comfortable. Amazingly, this brand of socks keep your feet warm and dry in the winter months and cool and dry during the summer season. SealSkinz socks can be worn to run or jog in every season.
