Super Comfortable shoes.
Size: 11, Color: Charcoal
I purchased these Hey Dudes for my husband. His feet always hurt. The moment he put these on he was so surprised at how comfortable they are. He loves the color and how he can dress them up or dress them down. The material is sturdy and comfortable. He found them great to wear and bring on a recent cruise we took. Comfortable to wear and walk around all day in and wear them at night for dressier nights.

Normally size 11 1/2 and these are just too small
Size: 11, Color: Grey
They are cool and comfortable however I’m just in between sizes. My toes tend to jam into them, but I still wear them and they look great
