Do Nike shoe sizes run large or small?

Nike shoe sizes tend to run on the small side. It is advisable for shoppers purchasing Nikes to add at least a half-size to the size they normally purchase.

For comfort and ease, it is important to know how different manufacturers size their shoes. Additionally, consumers should measure their feet before buying shoes to make it easier to find the proper fit. Many shoe manufacturers, including Nike, have sizing charts available online, so shoppers can find their size easily by consulting the chart. This is especially useful for shoppers who are ordering shoes online,without the opportunity to try them on in the store.
