I bought a pair of Ecco sandals to wear on a three week trip to Europe. I wore them before I went on the trip and they seemed fine. After one day, my feet began forming blisters and continued to form them during the rest of the trip. I had to buy an expensive pair of tennis shoes and padded socks to protect my feet so I could walk! Thankfully, the Walking Company took them back. My feet are still healing after I've been home a week and a half!
