Velvet-like exterior, adjustable side buckle, elastic in strap to allow it to stretch, and peep toe opening. Worn a few times. A few scuffs/marks that are noticeable when examining closely but not when worn. Still lots of life left. I can no longer wear high heels, so that is why I am selling them. From a smoke free home. Combination of leather and man made materials. Measurements: platform- 1 1/2" heel height- 4 1/2"
