I too went with the EA blue sock option. They were a little too roomy right out of the box (length fit perfect... guess my feet are skinny). I washed/dried them this morning to shrink them a bit. They fit fine now.
I also picked up a pair of the dotty gloves and half-mitts. Today was too warm for the dotty gloves but the half-mitts are awesome... wish I'd bought them earlier in the winter. easy on/off, they hang on the wrist via elastic, quick free fingers for camera usage. highly recommended.
