I'm drawn towards the bright colors,
But a neutral black or navy makes more sense.
Or silver would be a pretty cool neutral too.
I have one other requirement: they have to have a fairly high-reaching top part, as my size ten monster feet tend to look even more boat-like when the top of my foot is open and free.
