Back in the day, boots were allowed in eq; but not in the hunters. The logic being that hunters are judged on quality of movement, and a good hunter should not need boots. Since eq is judged on the rider, putting equipment on the horse that advertises they have a movement fault is not a problem. Many different types/colors/styles of boots are permissable in jumpers.
However, you need to check the USEF rule book or someone with knowledge of the circuit you'll be competing in. I'm not sure you're getting good info from your current sources.
The boots you linked to would be suitable. Leather, plain and unobtrusive. Good choice.
