I don't normally wear socks w/ my crocs (and I wear crocs every day, they have really helped my foot and back pain) but at WDW the kids and I all needed to wear socks w/ them. At home, I just don't walk the 6-8 miles in a day that I do at WDW. Word to the wise though. Take off the socks before any "wet" rides. When we get off, I just wipe them off w/ a chamois (or even paper towels) and bingo, dry feet for the rest of the day. They are also great when it rains - use the same strategy. I also wear the low ankle socks, the no show tend to slip down under my heel for some reason. Yeah, they're probably ugly, but what do I care?
