Never wear seekers/athletic shoes when visiting EU because you will be walking on a lot of cobblestone streets and seekers/athletic shoes do net have the necessary high quantity cushioning needed to protect your feet on these rough stone roads. Over the course of five decades of EU travel, here are the shoes I've found should be used in EU. #1: any shoe with the classic Vibram sole. Cabelas has some & all Rockport Walkers used to-- my most recent pair of Rockport walkers do not have the good Vibram soles. #2 Natural Balance high end walking shoes. I've only recently started wearing these, but I suspect they may rival the Vibram, #3 Sketchers high end walking shoes-- super comfortable and meet the minimum needs of protection from cobblestones.
On top of that, all these shoes are more comfortable for a lot of walking than are seekers/athletic shoes.
