After the Isle of Zaro's speak to The Enlightment about caskets, he will say you need 3 quests required to open these caskets which cost 500,000 coins each from him. the boots are 1/50 chance of recieving, when you find the casket with the boots it will come up with a discription which you will choose which ones to take.

During the Isle of Zaros, Commander Kaylin wear's the boots and Commander Tara wears the lightstone boots, during the final fight, you will need to defeat commander Kaylin (level 650) after the fight he will transform into a level 1039 Zamorak Commondora. Defeat it with Kaylin and you will see each of there boots go into the sea causing them to be locked in magical caskets.
