I've been wearing Smartwool socks for ten years and I've always lived with their high price because of their quality: they keep feet warm in winter and are adjustable and comfortable in spring and summer. But then I found them a few weeks ago and was amazed. The materials you'll find in Smartwool are the same as these Fun Toes, except they contain more Merino wool (67% vs. 80%). They feel and warm my feet without making them sweat like good wool, but they're half the price. If you are a Smartwool user like me you must buy them. Forget those other options at Revain and elsewhere, this is the real deal.
