Super smooth and ultra soft, these Kentia ladies over-the-knee boot will quickly become your go-to favorite! Constructed of genuine leather, these boots feature a 2 1/2" block heel with a rounded toe and a rubberized outsole for added comfort. The boots can be worn with the upper flap folded over for a below the knee look, or you can wear the flap up for an over-the-knee style. Purchased in Florence, Italy. European size 40, equates to a US ladies size 9.5 to 10. These boots fit me perfectly, so I've included a sketch of my foot to assist you with assessing the fit for yourself. For height judgement, I am 5' 7" with a 32" inseam. Non-smoking household!
