I purchased these to wear with sandals, and I am very pleased. Yes, I know, wearing socks with sandals is geeky, but lightweight 100% cotton socks feel great with sandals -- less sweaty.  I got the natural color, and it doesn't bother me that a bit of the sock is exposed.  At first the fabric between the toes feels a bit uncomfortable but I got used to it, a bit like wearing flip flops.
