ToeSox is the best brand to buy, as I have discovered. I recently found shoes with humongous toe boxes and they come with the recommendation of toe socks so I started stocking up. These are the most solidly constructed and the most comfortable, with a band for arch support and another at the ankle. The toes are well-defined so that there is zero excess material or pinching. And they hold up well in the wash (I forget what is recommended as they have no permanent care label, but I've been running them on the hand-wash cycle, cold water, and hanging them to dry).
