Absolutely. Running socks go a long way in increasing the enjoyment and effectiveness of run training. First and foremost, they keep your feet cool and dry, removing the moisture that can add friction and cause blisters. They also act as an essential barrier between the foot and the shoe, eliminating friction and hot spots.
They are undoubtedly more expensive than regular socks, but can make the difference between a fun day on the trail, and painful blisters — or worse.
Additional padding on the soles of running socks provides essential cushioning that reduces foot strike impact as well. Compression socks help you run longer and recover faster. After your running shoes, a good pair of running socks is a runner’s most important piece of running gear.
