The McKim sandal
I seriously want these in every color. I just received this turquoise pair today and looove this color. My gold and silver McKims are getting worn out from so much wear. They are so comfortable, and I am very picky when it comes to shoes (well, actually when it comes to a lot of stuff!). I can wear my McKims ALL day long! Initially I thought the little metal ring would hurt the top of my foot, but that is not the case at all unlike some other brands. I do stick to the all regular-leather version, though, because I don't think patent leather is as soft.
The McKim comes in this cute Lilly box with a shoe bag in Lilly fabric which is very handy when traveling.
