The Nightmare Boots is one of the various feet-based equipment that can be acquired by the players in the Nightmare. It can be purchased from No-Legs in the Inside (Blue Door) at a price of 250,000 gold. Other viable methods of acquiring the Nightmare Boots include the following:
- A possible reward from the Guttermouth Cells.
In appearance, the Nightmare Boots are short, pitch-black shoes accented with what appears to be glowing yellow 'eyes', curly nightmarish roots, glowing yellow sockets, and the finer details of a nightmare-fueled monster's face.
When worn, the Nightmare Boots will provide 8 armor points, slightly increasing the player's protection. It also provides 7 walkspeed points, making them slightly faster, however, this comes at a cost of deducting 20 jump boost points, forcing the players to be on ground-level at all times.
To counteract against the deduction in jump boost, the players can simply wear the Peapod Necklace to 'neutralize' the effect.
- Angel Wings/Dark Angel Wings will still activate whether or not the Nightmare Boots is equipped.
- Both the Otherworld Boots and the Nightmare Boots are commonly dropped from The Lost's boss. As a result, the nickname 'Boots' has become synonymous with the names of the items.
- The Clown Shoes and the Nightmare Boots both share the same model.
