    Great Looking!
    Size: 10 Wide, Color: Cognac
    I absolutely love my Marc Joseph New York Men’s Hill Street shoes. The comfort is incredible, the style is sharp, and the hands‑free technology is honestly a game changer. Sliding them on without bending down feels like a small luxury every single day. I’m impressed enough that I’m already planning to purchase more pairs.

    pretty but did not fit me well
    I personally found these hard to keep on my foot. I did like the look of them, and the heel height was nice (not too high, but also not a kitten heel). If you have a wider heel, they may be better suited for you. Pretty, classic, understated shoe.

    Back Strap too Loose
    Size: 8, Color: Platina
    Pretty shoes, but the back strap felt so stretched out I couldn't really wear them. It would have been effort to walk in them.

    Great office space divider without being suffocating
    Color: Black, Size: 4' Wide x 6' Tall (Fluted)
    This is a nice option for dividing up your office space. It's lightweight enough to be moved when needed, but large enough to create a sound and sight barrier between desks. The window design at the top also allows light through so that you don't like you are boxed in. Overall, this is a great office divider. It's well made, large enough to make a difference, and portable if you need to move it. And it does this without making you feel like you're in a box thanks to the fluted clear window at the top. It does the job I need it to.
