I work in a casual clothing store part time in 5 hour shifts (with one 15-minute break). We cannot wear flip-flops, but toe ring sandals are fine. These are SUPER comfy. I wear a size 6 or 6-1/2M, ordered a 6....a perfect fit (length and width). Great cushioning and arch support. In fact, I still wear them when I get home! The toe ring is very comfortable....and the top of the sandal, which is a stretchy spandex type of material, gently hugs my foot which allows me to walk full speed without worrying about slippage.  Excellent comfortable and very cute casual sandal. I've received many compliments on them (ordered the aqua). I HIGHLY recommend them to anyone.
