I just received these in the red s textile. I ordered 1/2 size larger based on trying on similar clarks instore.  They are fine except, even though I have a low instep, the top front edge is tight and leaves a mark on the top of my foot.  I'm going to keep them and try to somehow stretch this part so it isn't binding.  Other than that.....at 9 1/2 they are very comfy and make my foot look small! lol.
