Sad to say, I bought a pair of Eccos specifically for my Europe trip and they did not suit me. I suspected this since I test-drove them for a few weeks beforehand, but they were a major disappointment. I have plantar fascitis (sp?) so my shoes make a big difference, I had to mix and match all my various inserts and appliances and tapes and those shoes still were not comfy. They also looked really funky.
So buyer beware, all our feet our different and not all the highly-recommended shoes will work for you. You might want to use an outfit like Amazon or Zappos that allows free returns and try out many, many pairs before your trip.
