It's very warm! Perfect for cold days! It has good height and I think it's non-slip! I loved them, so I took good care of them! The calf area is fully lined with sheepskin and is warm! You can fold them over to adjust to your height and fashion! The leather inside the boots at the toe area is a little peeled, but would it be okay for those who don't mind? There is scuffing on the inside of the heels. Heel: 3cm Total boot height: Approximately 47cm Inside circumference of the shaft: Approximately 36cm These are being sold at a low price due to their condition, so please purchase after confirming the details!
