Lucky Brand booties have a back zip, side buckles and stacked wood heel.I must say, there is no size listed on these anywhere and I think that Lucky Brand often just puts a sticker on the bottom. I believe these are between and 8 and an 8.5.I now take a 9 and although I can put my foot in, I could not comfortably zip the back up. With that said, please check the measurements I have listed against your other boots that fit.Toe to heel approximately 9". Widest width at sole 3.5". Heel height 3.5". Total height of bootie 7".Excellent pre-owned condition.
