These are perfect! I am not a runner, but a nurse on my feet most, if not all, of a 12 hour day. The cushioning in the arch is just enough to be supportive, with out making the sock too warm. The cut is perfect, hitting just above where both my Nike's and Asics hit. Have the black version, and love the little pop of color, but wish there were a navy blue version with the same kind of pop!
