Swamp boots

Swamp Boots are specially prepared waterproofed footwear, which are designed to protect those who wear them from the sicknesses associated with walking unshod through noxious swampland. They appear in Ultima VI, Ultima VII, Ultima VII Part Two, and Ultima IX.

Description
The swamps of Britannia and Serpent Isle have the strange property of infecting those who walk through them with the toxins within them - seemingly passing poisons to wayfarers through the soles of their feet. To combat this hazard, waterproofed swamp boots have been developed, which allow their wearer to wade through all manner of mires and bogs without fear of ill health. Popular amongst adventurers for obvious reason, these boots have been available since the days of the gargoyle war, and were long sold by provisioners and armouries for an inexpensive fee.

During the last years of the Age of Armageddon, however, knowledge of how to make and treat swamp boots appeared to have waned, as only a single pair could be found throughout the realm, having been abandoned in the dungeon Hythloth. Nevertheless, this single pair would serve the Avatar well should they find them, as their protective properties had not deteriorated in the days since they had been cast aside.

Trivia

 * In Ultima VII, a pair of swamp boots which were allegedly worn by the Avatar could be found in the Royal Museum in Britain.
 * In the SNES Port of Ultima VII, only a single pair of swamp boots could be found in Britannia - within the house of Rudyom the mage.
 * In Ultima IX, swamp boots would protect the Avatar from swamp-borne poisons, even if they were completely immersed in swamp water.
