Theses ECCO shoes are very well made, and they look good too. Unfortunately ECCO's sizing is an issue. They only offer a "one size fits two" option (9-9.5, 10-10.5, etc), which is likely to be problematic for most people. The actual length of the shoes is perhaps a size up. I usually wear size 11, but I often buy tennis shoes size 11.5. So, naturally, I bought size 11-11.5 shoes. Guess what? They are a whole half-inch longer than my feet. Feels like it's size 12. I can still wear them, but they look and feel longer than they should. Perhaps one can go a size down, but I am not sure if it's not going to make them uncomfortably narrow. Width-wise, these are a tight medium, and smaller shoes can be good in length, but too narrow. Generally, if you have wide feet, then stay with your size. If, however, your feet are narrow, then perhaps you should buy a size down. These snickers would be perfect if they were a bit shorter and a bit wider...I wear a size 16 and it is difficult for me to find shoes except when it comes to any Ecco! I love these shoe and own many pairs of different variants. They are always true to size and have a comfort value that surpasses many other shoes.Super leather casual shoe. Quality and design I expect from Ecco. They do run big though, but if you've bought Ecco's before, the size you have worn will be accurate.Highly recommend!Beautiful shoe fit like a glove highly recommendedStill trying to find a compatible slip on shoe size which appears to be quite different than your regular laced shoe size. I think that in order for the “slip on”feature to work and yet be comfortable one will still need to “try before you buy.” Trying a smaller size than your regular shoe size may get you started in the right direction toward trial and error.I like it very much, very comfortable and soft for my feet. I use it every day.The shoes are so wide they do not provide good support for the feet - not like the first pair I had. Furthermore, the first order sent was a pair of red girls' running shoes size six, which I returned with no problem, but I wondered how they could get it so wrong. I will likely not order again.
