I bought the Marie flats because I liked Dr. Martens Christina flats, but they were a little too narrow and oval for me. The shape has narrowed considerably since the old days when they were a respected, sought-after brand made in England, and they keep making them ever narrower. I bought these Marie flats in Blueberry Cartegena, thinking they would be just like the Christinas, but easier to wear because the leather was softer. Unfortunately, they're not even close.

Pros: The Cartegena leather is great--very flexible and soft, but not shapeless--and the blueberry color is an absolutely stunning medium-light blue-violet. It almost glows. The color must be seen in person to appreciate it. I recommend getting a pair of DM boots in that color, but not these flats.

Cons:
Size - Dr. Martens sizing can be inconsistent from style to style, but I usually wear a UK 5 in DMs (US Women's 7, medium width).  I ordered the UK 5 and they were a full size too long, and way too narrow. They are so narrow as to almost be a specialty size, so if you have trouble finding shoes narrow enough, these might be for you, but order a size down.

Shape - These shoes are strangely pointed, like they can't decide whether to be a practical oval or a high-fashion point, so they got stuck awkwardly in between. They also did not cover my toes all the way, barely coming up halfway over my toes. I had to return them. Normally I wouldn't give a bad review for shoes just being a style that's not to my personal taste, but they looked and felt so weird, combined with the bizarre sizing, I had to speak up.

I just wish Docs would go back to their vintage toe shape from the 1980s and '90s. I would give my right arm for a pair of Dr. Marten flats in Blueberry Cartagena, with a high, round, wider toe box like they used to make. I don't understand why DM just keeps making the shape of their shoes worse and worse, especially now when '90s fashions are coming back into style and people are feeling nostalgic for the old Doc Martens.
