Fit like a glove - the quality is noticeable, so it feels great against the skin! I walk about 5km per day - as do good socks a big difference. For I am very, very happy having found the Falke running socks here. Did I also like a 2nd pair ordered.
Most socks easily get holes or are of poor quality (can be felt immediately). If I had to recommend a brand for running socks - then without hesitation HAWK.
