I am wearing the Yosi Samra Sahara flat today and they are very comfy. I usually wear a 7 1/2 and have wide feet. I got these in 7 and they fit perfectly. No arch support in these.

I bought these in taupe because I wanted a fairly neutral shoe that would blend in with whatever I was wearing. The taupe is not taupe but definitely a light gray. I would rather it be more of a "greige" (gray-beige) color but these are still ok for what I need.
