Light but average
Size: 10.5, Color: Black
Three stars. These are very lightweight and seem fine for the price, but the leather felt a bit too thin for what I was looking for. I didn’t even end up trying them on because they just didn’t feel like they would hold up long term.
They’re not bad if you need something inexpensive for occasional wear, but I wanted something that would last. It felt like they might scratch easily, so I decided to return these and go with a more expensive option instead.
