I love these. They are so comfy I forget Im wearing them. I did order 1/2 size bigger than my normal 8.5 and the 9 fit perfectly. I like that the heel area is not loose at all. No floppy shoes! Also, theres is no toe cleavage. The sides of the shoe are a little low for my taste, but it in no way affects the wearability of the shoe. I didn't need any break in time for these to be comfortable.
