andychris14,
Moleskin is a protective covering for blisters or for areas at risk for blisters.Such as places where your shoe might rub. It is sold in rolls and the rolls are in a box. It says moleskin on the box. I have found it both with foot supplies and with first-aid care items. You shold be able to find it in any drug store or somewhere such as wal-mart. I am sure anyone would be glad to point you in the right direction.
Just a note. It is much easier to prevent feet problems at WDW than try to treat them. We always carry moleskin but only DH who has trouble with his feet anyway has needed it. A few tips that help us is to purchase new shoes about a month before your trip and wear them in good before you go. We swear by NEW BALANCE but lots of other people have their favorites too. We also wear think socks but a lot of people find they do better with two thin pairs. We spray our feet with SURE and let them dry before putting on socks and shoes. We also try to keep our feet dry in the parks. If your kids will want to be in the fountians, take along a change for them. My nephew got terrible blisters from wet shoes and socks! There have been some great threads on Disney tips on foot care also.Have fun packing!!
