I bought these sandals in the silver color in size 7/8.  I normally buy shoes in a 7.5 but sandals in a size 8 because of my long toes, and these were just about right lengthwise.  On the other hand, they were somewhat narrow, so if your feet are on the wide side, you may need to size up or buy a different type of sandal.   In the picture I attached, you can see that my big toe hangs over the edge just a little, but to be honest, I had worn them several times and never noticed that fact until I took that picture, so maybe it was partially how I was standing at the time.  (Also, a bonus in the picture: you can see my cat admiring my sandals aka wondering why the strange human is taking pictures of her feet.)  I've worn them several times so far and they are as comfortable as any sandal I've worn, and the straps around the ankle provided more support when walking than an ordinary sandal.
