Skeletal boots are a members-only piece of magic armour. The player doesn’t require any stats or need any quests completed in order to wear the boots or gloves, unlike the other pieces of the Skeletal armour set.
To obtain skeletal boots, either receive them as a drop from Wallasalkis or trade with another player. The player does not need to wear the boots along with the other pieces of the Skeletal armour set to have an honorific added to their Fremennik name in Rellekka. They are necessary to make the armour into a set to store in a Costume room.
