I really love them. The heel is higher than I usually wear but I can wear them for an hour or two. The leather quality is amazing. There is no zip and I have pretty substantial calves but I can just pull them on. I haven't worn them enough for them to get slouchy but they may with time. In terms of sizing​,​ it's fairly true to size - I'm between an 8 and 8.5 and the 8.5 was good. I feel like many higher end brands run smaller.＜abbr＞​,​​,​​,​ ＜​/​abbr＞
