Boots

The basic Boots, Bear Boots, Dragon Boots, Freudian Slippers, Pegasus Boots, Rocket Boots, Sexy Shoes, Sneakers, and Spirit Slippers are items. They share an item slot. (Consider all of them to be Boots variants.)

Bear Boots

 * Choose to move forwards or backwards 7 spaces, killing all players on the landing space. (You technically kill them before moving.)

Dragon Boots

 * Choose to move forwards or backwards 13-16 spaces, applying 1 stack of Fire to all players within the spaces moved.

Freudian Slippers

 * Choose to move forwards or backwards 5-7 spaces, learning 1 random Learnable Feat known by each living player moved through if possible. (Unlearned are prioritized over learned.) (Needs elaboration on the order in which the Feats among multiple players are learned.)

Pegasus Boots

 * Choose to move forwards or backwards up to 10 spaces; if you hit any player in the 10 spaces, you stop immediately on their space, moving no more spaces. They move 2-3 spaces in the direction you were moving and are Incapacitated. (Needs testing on if this can affect multiple players.)
