I admit that I have tried on the shoes in a local business, so I could be sure in size, although I'm wearing Teva for years and the size really know. The fi 4, however, are a class better than the ones I have been wearing, but for the same price. Because I certainly bought the top product of Teva. Here are my other Teva already 3 year old and still like new. Wanted to just do something good, like women do it, too, with their shoes.
