From NO. 6, the cult clog-makers in NYC, this is a gorgeous and cozy fur-lined knee boot that's very comfy and perfect for cool temps. The quality is amazing. Fur, suede and leather are all nearly immaculate. Bottom treads show barely any signs of use - see pics. I'm typically a 39 in NO.6 but sized up to a 40 since the lning is a bit thick. I have a shorter pair and they have worn down over time. HEEL is 3" and from bottom of heel to top of shaft is 18". You can fold over and wear shorter, or full to knee.
