Comfortable and stylish
Size: 12, Color: Black
I'm very pleased with these shoes. I rarely write reviews, but these are extremely comfortable and stylish. I bought a black pair and a brown paid. Many times I have to get a wide, but the standard size 12 fits me well. Easy to slip into, yet still snug while walking.
I feel like the price is reasonable too.
Good cushioning, not too thin of a sole.

Good looking shoe.
Size: 9 Wide, Color: Cognac
It's a good looking should which is true to size. Quality is good. However, it is not leather. Inner and outer covering are man made. For me, it's okay. I ordered a 9W which I knew would be no more than a triple E width. I'm actually a quadruple E width so it's taking a little longer to break in. I won't be using these as often as at this stage of my life, I don't have that have functions that require dressier shoes. I'm happy with this purchase, a good value for the price. The slip in feature works well like my Sketcher slip in.
