Nice quality! BF approved.
Size: 9, Color: Olive
I got these for my boyfriend and he loves them. The color green is really nice and the quality is really good. I would recommend doing a waterproof/weather treatment to them if you plan to wear them outside. His got water marks on them already and I didn't treat them. Important note: If you have narrow feet these will work great, but if you have wide feet it might be an issue. They are true to size.
