When you are training for or running a marathon (42 km) — or even a half marathon or long-distance race — your feet are subjected to hours of continuous stress: repeated strides, repeated impact with the ground, perspiration, friction, possible swelling of the foot, temperature variations, muscle fatigue, etc. ‘Classic’ or poorly fitting socks can accumulate moisture, cause friction, blisters, irritation or discomfort, especially over time.
Socks specifically designed for marathons optimise comfort, breathability, moisture management, fit and protection — making the difference between a painful marathon and a successful one.
