Kenneth Cole Reaction Platform Heels made from man made materials. They have an elastic section near the buckle which makes them friendly for thicker ankles and prevents the heel from flopping. the block heel is very sturdy and they are stable to walk in. I only wore them for 2 events and they are still in good condition. Women's size 11 medium width. Runs true to size. #office #workwear #formal #dance #retro #y2k
