Yes they do run a little wide compared to the Teva brown and black leather ankle boots (non-perfect) boots that I own. But not so wide that my foot isn't supported. They are leather and will conform to my foot.
I meant Non-perf! They are perfect! Autocorrect changed my typing!
These come in a medium width. According to our fit team this item is running true to size.
I have a narrow foot and had to get a 1/2 size down from my regular Teva size for these (I wear an 8.5 in Teva sandals, but the 8.5 in these were too loose all around). From this experience I would say they run a little wide.
