New Favorite Work Shoe
Size: 9.5, Color: Black/Ivory
These Cole Haan Grand Crosscourt Daily shoes have quickly become my new favorite work shoes. They’re incredibly comfortable right out of the box, with just the right amount of cushioning and support to get through long days on my feet. I love that they look sleek and professional while still feeling casual enough to wear anywhere. The build quality is top-notch—durable materials and solid construction that make them feel like they’ll last a long time. Overall, these shoes strike the perfect balance between comfort, style, and practicality. I can honestly say I look forward to wearing them every day. Highly recommend for anyone who spends a lot of time on their feet but doesn’t want to sacrifice style.

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.
