Not as expected
Size: 11, Color: Light Brown-pu
Unfortunately I ordered mine before the last review that said these are slip-ins. I'm not understanding that sock thing. It makes it harder to put the shoe on (So opposite of a slip-in) And it pulls your sock down (pictures show them wearing one) constantly when you're walking. And apparently the shoelaces are just for looks? But they're so long you have to tie them anyway, and as someone said the laces are bad. Skinny wax. I'm going to give this three stars though because they are very comfortable. So at this point in time I don't know if I'm going to return them (I got brown) as there aren't too many sneaker dress shoes (arch support) there's dress shoes that are more comfortable (but not sneaker comfortable).

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.
