This is my second pair of Merrell Pesaro Slide-ons. The first pair was recommended at a high priced department store.  I was going to an amusement park and the sales person said I would have No blisters, and No sore feet, and they would stand up to the water rides.  I was sold but skeptical.  Not only was she right but they lasted a long time and my European High arch didn't give me problems. I just bought a pair for my sister who has plantar problems in her feet, and can no longer where flat flip flop style shoes. I looked at many stores but they don't carry this style anymore?? Thank God for Amazon.com!!!!!!
