...get high-performance bicycling socks and you won't notice wet or sand in your shoes so badly.
You can get bike socks from nashbar.com, performancebike.com or coloradocyclist.com. Problem is they're $9.99 a pair. If you're not into wizzy colors or designs go to Target or Costco and get their low cut athletic socks. They're probably about half the price. As long as they're Coolmax they'll work fine.
