Not quite flat, not quite a kitten heel. The 1.5 inch heel is an in-betweener, but don't discount them quite yet. 1.5 inch heels help to elongate your legs and often times are just what you need to keep your pant hem from dragging in between visits to the tailor. Whether you're looking for a pair of knee boots with a slight lift, or a sandal that offers more support for the arch of your foot, shoes with a one and a half inch heel are the perfect compromise.
