"Much better than others"
Last year I bought a similar pair of boots from Tiktok but I was so disappointed with the bad quality. My friend recommended these, and I have to say they are a million times better than the pair I bought last year. The leather is glossy, and the shape is beautiful. They look really good on and I love how comfy the sole is. I have been wearing them mostly with mid length coats and jeans, but I have also worn them with a maxi dress and they looked very cute. The stretchiness is a plus but honestly i just love how they look with most outfits. I have only had them for about a month so I'm not sure how long they will last but my first impressions are really positive!!

"The real deal"
I have been shopping for knee high boots my whole life but never found a pair that fit me perfectly. I usually size up and wear insoles so that I can get them on, but even then they are just really uncomfortable. This made me stop buying knee high boots until a few months ago when I saw a Facebook advert for boots that apparently are extra stretchy so they they fit wider calves. I bought a pair and a they arrived a few days later (I stay near Philly). I don't normally leave reviews but got to say these boots are the real deal. As they say material is very stretchy and I can easily get my feet inside and haven't had any issues with them slipping down when wearing. I really like the chunky sole and it is very comfortable to wear for long periods of time. I must say these are a super pair of boots that look the part as well.

"Just waiting for Fall!"
Very cute and versatile boots. I wasn't sure how to style them at first since they are a bit of a statement piece but having watched some videos on Tiktok I think I am totally ready for Fall season!! Just waiting for it to get a little colder so I get some more use out of them...
