    Nice so far.
    Size: 6.5, Color: Molasses
    Comfy. They were tight the first day across the toes but as I've worn them a couple times they are loosening up. The sole is forming to my foot. These are very much like Doc Martin's from the early 2000s. Not sure about quality since I haven't had them for very long.

    Not the best

    They are cute but they have a bit of an odd fit that isn’t great for people with narrow feet. They look too dressy to wear with super casual outfits in my opinion. I think the Ugg golden star sandals are much comfier. If you’re wearing these sandals for a really short time they’d be okay. After wearing them around my house for a little while I decided to return them since they started to hurt my feet.
