Seriously, you can't imagine the trouble I had. Last time we went, I actually missed a ton of stuff because my feet hurt so bad. I stayed home one day so I wouldn't hold my family back - I skipped all the pavilions at Epcot. I was seriously considering a wheelchair it was so bad. I ALWAYS get really, really bad blisters - I'm prone to them anyway, and the heat and humidity makes it so much worse. Really - I can't overstate how bad and gross it is. My husband could barely stand to look at my feet. I get them under my toes, on my instep, and on the outside of my heels. So what REALLY works? Other than wearing good running shoes, has anyone found what really works - powder, blister sticks, moleskin - or is it all in the socks?
