i have several pairs just like the last ones you posted, and i love them. i'm digging the la redoute ones, too. the first ones look like they are made poorly and the sides would stick out and look gappy on your feet.
I like all of the ones you posted, but I just bought these from Target for $17 (thought you might like to know, as I needed a cheap and comfy pair and these fit my needs/wants):
