Osiris was always true to form. When you acquire them, the colors are more brighter. The quality is better. The fit is perfect. They're just plain comfortable shoes. The best way to find out if a shoe runs true to size is to buy a pair and see how they fit. If they don't fit properly, then you should probably go down a size. But remember, this recommendation is based on our experience with Osiris products; we may have been lucky with their sizing or maybe they just happen to have a wide variety of sizes right now. Osiris only carries men's shoes and half of those are work boots. So if you look around there might be some options for non-work use. It depends on what styles they carry but since it's limited we wouldn't expect anything else but work boots from them. Work boots are usually a little larger than regular shoes so if you fit into one of theirs you should probably get a size smaller otherwise you might want to consider buying work gloves instead. If you're looking at different brands they all vary in size.
