Great shoe for the price
Size: 9, Color: Black
My son needed a dressy pair of shoes. Decided to try these for the price. He loves them and has worn them several times. They still look great and he says they're comfortable. We ordered his regular size and it fit perfect. We’re very happy with this purchase.

Not a great fit
Size: 12 Wide, Color: Dark Brown
I got these hoping to have a good fit and comfy shoe. They do look very nice and some might like them. I got two different brands the same day these and another one ,both the same size and they fit widley different. These have a very long and pointed toe that made that uncomfortable and hard to walk in. I would have to try out other sizes to see if I could find one that fit better but I dont want to go through 5 pairs to get a good fit. That is a downfall of buying online. They did seem to be made well and like I said the looked good but the fit not great.

Classy and affordable

I purchased these for a show I costumed at the local community theater. The fellow that wore them said they were comfortable and fit well. They look very classy and came as described. Good price for a nice shoe!
