TRY EVERYTHING ON, EVERYTHING YOU CAN GET YOUR HANDS ON.
Salomons are generally for people with slimmer feet and high arches. Not to say other feet don't fit, but thats the trend I've noticed. I've got fat ankles and feet, so the f20's didn't cut if for me. My friend has slim feet and high arches and she never wants to take her salomons off. She will actually wear them around her apartment.
That thing I do to escape the world and have fun with my friend
