Aaaaand they're done! (They really do match, right down to the last row. The picture just makes them look like they ended at different places. I think I was curling my toes.)
The yarn is Supersocke Summer, if I recall correctly. It's a wool/cotton/nylon blend, which my feet like, but my hands don't. It's kind of splitty and doesn't really have the bounce of wool, although it's not terrible.
The shoes (my new favorites) are Born Joey clogs. They're super comfortable, lightweight, and go great with jeans or pants. They also show off handknit socks nicely. I got mine at theshoemart.com, but they're available all over online.
I don't know how all you sock knitters get decent pictures of your own feet.
