@Fakaiha Zaheed I got some CEP compression socks with a gift card I won here (thanks, @Caroline Claassen !) and loooove them. I don't think they improve my actual running, they're just really comfortable and the coral color goes with my shoes :D. A pair of running socks I bought that I thought actually made a difference in terms of performance were wool-lined double-lined socks for autumn. They really helped prevent blisters when my shoes got wet, with the two linings sliding against each other instead of my foot.
