Yes, it's OK to wear sneakers for business casual. Sneakers are a great option for any occasion and are suitable for both men and women.
If you're wearing sneakers with a suit or business casual pants, consider adding some color or pattern to your outfit. For example, you could pair a patterned shirt or tie with your sneakers for a more formal look. Or, you could wear an athletic-style shirt under your suit if you want something more casual.
Sneakers also work well with all types of bottoms: jeans, khakis, shorts and other items that are typically worn at work. When wearing sneakers with shorts or jeans, make sure the length of your legs is appropriate for the length of your shoe. This is especially important if you're wearing athletic shoes or boots (which tend to be longer than dress shoes).
