Just bought myself a pair of Salt Water Sandals (the classic style). My feet fit perfectly......is there supposed to be any buffer/gap? My feet don't hang off or anything and the width is good. I'm afraid if I go up a size they will look too long?

i usually like a buffer gap when wearing shoes, unfortunately no half sizes in this brand....but maybe it's ok because they are sandals? What do you guys think? How do you wear your Salt Waters?
