I bought these cleats because the description says SAE sizes. However, when I received them, the outside of the box said "150PC RUSSIAN DESCRIPTION RANGE" and weird metric sizes on the inside. So if you are looking to buy odd sized Chinese made Russian cleats then this is for you but I am very disappointed that they are not the sizes as advertised. In hindsight I had to scroll through all the photos to see that the description did not match the product.
