Ondo Socks

My personal pick is the wool (even in the summer!) but they also have cotton. And they have an even lower cut no-show than these. I've had them for a while and they hold up. Comfortable and they have a little silicone strip at the heel that keeps them from slipping. I had previously been a Smartwool fan, but they're too expensive, and their no-shows are not constructed as well as these. Note the price is for a multi-pack.
