I sometimes wear socks with sandals. 2 reasons: Firstly, British weather being what it is, the summer is pretty short so I might spend 9/10 months of the year not in sandals. So when I start wearing sandals again my feet don't feel that comfortable in them to start with. So I wear socks. Secondly, in the evenings, when shoes + socks would be too hot for a whole evening but sandals would be too cold. If anyone has a problem with this, and I know lot's of people think they do, then I am just sad for you.
