They are very comfy and work perfectly for the shoes that I wear with them.  They are definitely not for the loafers but they work great with my booties and short boots.  The first time I wore them the heel was a little loose as some of the reviews said, but I washed them in the washer, and dried them in the drier.  Now they shrank a bit so now they fit nice and tight.  THese will be one of my favorite socks!!
