There are several classes of "normal" defensive equipment in Golden Sun and Golden Sun: The Lost Age, but in addition there are several other classes of "supplemental" equipment that you get under special circumstances and can equip for extra benefits in addition to the normal equipment you're wearing. The pieces of armor listed here belong to the Boot class of supplemental equipment, and as such they are equippable by all Adepts in each game. Almost all Boots are counted as Artifacts, meaning that almost all of them do not appear in the Buy menu of vendors. These are bought and sold individually and usually are unique, and if one appears in the Artifacts menu of a town's vendor that one boot can be bought by itself and then be sold by itself anytime afterwards to reappear in the Artifacts
