INSTEP: WILD DENIM WEDGE HAS AN OPEN INSTEP AREA, SO FITTING FOR HIGH OR LOWER INSTEP IS NOT A FACTOR ARCH: THE CONTOUR OF THE SOLE IS SLIGHTLY CURVED, VARIOUS ARCHES SHOULD BE ABLE TO COMFORTABLY FIT THIS SHOE WIDTH: THE COW CUTE IS GREAT FOR WIDE - NORMAL WIDTH FEET. SMALLER WIDTHS MAY FEEL THE NEED TO SIZE DOWN OR ADJUST THE BUCKLES ACCORDINGLY FOR A MORE SNUG FIT LENGTH: THIS IS WHAT PLAYS THE BIGGEST PART IN OVERALL SIZE. GOING UP A SIZE WILL INCREASE THE LENGTH OF THE SHOE.
