About shoulder width is good for balance, but if you have a lot of weight to carry then go wider. If you're like me and don't want to look like a freak, keep your feet about the same distance from each other. The key is to find what works for you. Some people can get away with having their toes turned in while others need their feet as close together as possible. There's no right or wrong here, just do what feels comfortable. If you have big feet like me, you might want to get a pair of snowboard boots that come up high on the leg so you have more room for your feet inside the boot. That way you don't feel like they're going to pinch too much when you stand up straight. Of course, there are also specialty boards made for people with large feet. These boards tend to be wider than normal ones and have larger holes under the footbed for your toes to stick through. This helps distribute your weight more evenly across the board and reduces the risk of you getting ankle injuries. Finally, make sure you get the right size shoe and boot.
