Are there football boots that can double as rugby boots?
Either type of football (Association or American) boots can be used for rugby. The only proviso is that American football boots usually have a stud (or studs) located directly under the toes. That is illegal in rugby (it makes rucking more dangerous) but it is easily solved by getting out your stud wrench and removing them. The the shoes will be perfectly legal. In some situations (generally backs playing on a hard, fast pitch) bladed soccer boots can be superior to rugby boots.
