Ham boots are worn by H.A.M. members. They are the footwear part of the H.A.M. robes set. When worn, players are slightly less likely to be kicked out of the H.A.M. Hideout when pickpocketing male and female H.A.M. members. Wearing this will not increase the player's chances of successfully pickpocketing, however.
They can be obtained from H.A.M. members while pickpocketing, by killing H.A.M. Guards, or via trading with other players. They are required for a level one treasure trail.
