I haven't had much luck finding places in the US that even sell a lot of the English shoes that I find appealing let alone a place that I could go try them on. Seems like you have to buy from places like Pediwear or Herring and cross your fingers big time. This has kept me from trying anything English. I'd love to have a shoe by as many of the English names as I could afford, but I will probably wait to see if the occasion arises where I am in England and can try things on prior to purchase. If that happens, I'm going with a suitcase that will be filled with currency on the way there and shoes on the way back.
I plan to buy a pair from the main countries that I visit.
In Madrid I picked up a pair of Meermins to cover Spain, but had I known better at the time it might've been Carmina. Regardless, what I paid for those Meermins was great value with the euro at 1.1.
