My husband wears a 9.5 U.S. Since these don't come in half sizes I ordered a 10. They were too small. He could barely get them on and they were too tight. I've orderd a size 11 to replace them and am sending this pair back.They do seem well made and look like they'd be comfortable. We like the thick hard sole on the bottom, and he loves the green color. For now, giving it 4 stars simply because he can't wear them but they do look nice. Will update when the new pair gets here.
