I was looking for a dress shoe for my fiance for our wedding. The day will be primarily outside, so we loved this style because its much more comfortable and supportive than a traditional dress shoe. The look of these is great, they are beautifully made and have a great color. My only complaint is that the sizing is a little off. They run pretty large. My fiance wears between a 9-9.5, but usually buys a 9.5 We had to buy 4 different pairs before setting on the size 8. He reports they are so comfortable and a great shoe, just know if you are buying for an occasion you might need to exchange for sizing. I would buy at least a full size smaller.

These were perfect for our tropical destination wedding

Size: 9.5 Wide, Color: 8/Tan, Size: 9.5 Wide, Color: 8/Tan

I bought these for my husband to wear at our tropical destination wedding. They are fairly lightweight so they didn’t add too much weight to the luggage. He needs a wide in some shoes, others he can get away with a normal width. He said he felt really good. I would definitely recommend, and I would buy again.

Nice look, nice price, but not durable

Size: 12, Color: 8/Black

I really like the way the shoes looked, and the price was good. Unfortunately, the seam first busted after only about 5 months. It has been about 10 months now, and the seam is busting all the way around the shoe.
