The last two times I went, I wore Nike sandles (type with a band across the top, and no heel). They were great because you could adjust the top band (velcro) if your feet swell...they are also waterproof. I'm like you, I hate wearing socks, and had no problems at all. Just be sure you use sun screen on your feet and calves, I got a horrible rash, which I am assuming was either from the reflection off the pavement, or burn.
