“I would like to get the beige in a 42 which corresponds to a size 10.5 in American sizes. I normally wear a 9.5 and was told on your website under the title " Closeout: " to order one half size up because they run small. My foot is slightly narrow and your one review on your website says that this shoe runs narrow so that's good but I'm wondering if I should get a 41 (only available in black) or a 42. Thx. ”
I would say you need to get a size 41. US size 9.5 should correspond to EU size 39.5-40 (in my opinion).
But really, be careful with a width of this shoes, they are not small because of length, they are small because of width.
If your foot tends to run small as well then it could be beneficial to order the smaller size, but I cannot guarantee that it would fit.
