how casual

[Mr. MacDougall]

London, New Year's Eve, rain. I'm wearing sandals---with waterproof breathable booties, naturally, but you can believe I'm wearing socks!

Have you seen the Acorn brand sandal socks? They're fun and colorful, and they're made of high-tech materials that wick moisture away from your feet. I've actually waded flooded washes in them, and had my feet feel dry within half an hour.

I wear either hiking boots or sandals with my kilt on a regular basis. I haven't tried tennis shoes but then I don't really like tennis shoes very much.

In the heat a lightweight kilt and whatever is comfortable on your feet are fine.
