Look and feel great but run a little bigger
Size: 10.5, Color: Navy Ink/Woodbury
My husband loves these and they look great! He is normally a size 11 but we ended up having to exchange for a size 10.5 because they ran a little big. Keep that in mind! But they are high quality and super comfortable.

Great Everyday Shoes—More Casual Than Expected
Size: 12, Color: Black/Optic White
Very comfortable and lightweight—great for everyday wear. Build quality feels solid, especially for the price. They lean a bit more casual than the photos suggest, but not in a bad way—still versatile enough to dress up or down.

Stylish, Comfortable, and GQ-Approved
Size: 9, Color: Navy Ink/Woodbury, Size: 9, Color: Navy Ink/Woodbury
I bought these Cole Haan Grandsport Journey Knit shoes for my husband, and he absolutely loves them. They’re stylish and really complete his outfits — very GQ vibes. He says they’re extremely comfortable on his feet and easy to wear all day. Great look, great fit, and definitely worth it. Highly recommend!

Extremely comfortable
Size: 10.5, Color: Navy Ink/Woodbury
As a manager for a very large corporate office campus, I do a LOT of walking. These shoes are a life saver. They look good, are comfortable, and so far, very durable. There are a lot of tile floors on this campus and when the shoes were new, they were a bit squeaky due to the soles adhering to the floors. Now they are as quiet as can be. I like them so much I asked for a pair in brown for Christmas - also awesome!
