Fast delivery. I wasn't sure about European sizing since I live in the United States. I have a size 9 feet. I bought her to work as a housekeeper in a big four star hotel. At work I am on my feet 7.5 hours a day. These shoes are comfortable all day long. These shoes are light on my feet and the good airflow keeps my feet from sweating. i live in texas It was 101 degrees outside and my feet still didn't sweat after running 20 minutes outside in the 101 degree sunshine. I'm surprised. I had a pair of Ecco Track 2 Lows which were very heavy but also very durable and comfortable. Seems to be a very good deal. If I buy them again I will try the next smaller European size. Instead of size 43 I will try size 42 for my size 9 American feet. I am satisfied with these shoes and I receive useful items in the mail.
