Great fit but Wonderful is wide
"I am a size 8 1/2, and the 8 fits me perfectly. I am a 'classic' Medium width, and the soles on Wonderful are just a bit wide for me. Sooo comfy, but I'm going to stick to the narrower soles (can tell it's a Medium because the model also offers 'wide' size, like this one doesn't). I still wear them regularly, just prefer them narrower!"
