I’m very happy with this purchase! I am 5’5, 150 lbs, my shoe size is 7.5 in women’s, and I purchased these boots in a 9. Definitely listen to what others are saying regarding sizing up! I only had a tiny bit of room around my feet so I threw an insole in, but I think this size was perfect everywhere else in my calves, thighs, etc. So far I have worn them once, but I wore them for 10 hours straight, walking a fair amount and dancing. Running sometimes LOL. I was totally comfortable until around hour 8 but it was the normal discomfort in the balls of your feet that you get from any pair of heels, especially after wearing them for 8 hours. The ankle support is great, wearing some thick socks underneath helps even more, and with the amount of lace and buckles you can really personalize the fit, although I think for someone slightly thicker the thighs may not lace fully. I didn’t roll my ankle once, which is impressive considering I hadn’t worn heels in around 10 years. Lastly, I got TONS of compliments. They really do look stunning in person. Highly recommend!
