As described on Lulus.com - 4" wrapped block heel. - Cushioned insole. - Rubber sole has nonskid markings. - All vegan friendly, man made materials. - Imported. My personal review, I only tried the heels on once. I can’t really say wether they are comfortable or not. I have very narrow feet and not a lot of tall heel wearing experience so to me they were a bit uncomfortable. That’s just my personal take, but they are super cute!
