Rubber boots

A pair of sturdy rubber work boots. They'll keep the sludge out, at least for a while.

With rubber boots, you can walk on puddles of toxic waste safely until they melt.

They do nothing to insulate you from electrically charged floors.

The boots help greatly in the Toxic Caves, where puddles of waste are plentiful. Two pairs of boots can be found in Trapper Town in Klamath, and another pair can be found in a locker in the caves themselves. Smiley also has a pair if you wish to steal them, but you should let him keep them since you'll be taking him out of the caves.
