I have really small feet and narrow heels that slip right out of flats and pumps that don't have straps. Usually I can get by with flats by using a heel grip, but a lot of times the thickness of the heel grip makes the shoe too tight. These straps solve that problem! As much as I love the look of strapless pumps, my feet are just not made for them. At least these have saved me money by not having to donate another pair of shoes my feet slip out of because I missed the return window. The straps were a bit too long for me, but it was very easy to poke a new hole in them and I cut off the excess strap. The shiny side matches my patent pumps perfect.
