Quality at affordable prices.
Size: 11.5, Color: British Tan/Ivory
Best old guy shoes. They look great and have support for feet. You don't want cheap department shoes. You will pay for that in your later years.

Check the size you need .
Size: Large
It did not meet my needs only because of the size. More suited for 8.5×11. I was looking for a 5x7 format solution. At bit pricy.

Good comfort, quality and classy
Size: 8.5, Color: Black/Ivory
’ve been wearing Cole Haan dress sneakers for work and travel, and they strike a really good balance between professional and comfortable. The biggest advantage is how lightweight they feel compared to traditional dress shoes. Most styles have sneaker-like cushioning, so you can walk or stand all day without your feet getting destroyed. The design is also versatile and look polished enough for business casual outfits but still casual enough to wear with jeans. They work especially well in office environments where a full formal shoe feels too stiff or outdated.
