Whirlwind Boots

This tool, that I will call "Whirlwind Boots" would be equipped in the boots armor slot, would have the same defense as  Iron Boots, and the Durability comparable to Gold Boots. When you hold "Shift" for over 2 seconds the player would begin to spin like a top and the longer its held the more you spin, when you release the "Shift" key the player will begin to dash forwards (In the direction the player was facing before spinning.) The speed of the dash is determined by the longer you hold "Shift." When you are spinning you can rebound off of mobs, players, and walls but you loose a bit of speed, also while spinning you can deal 5 damage with average knockback.

*Edit:

In short this move is literally the Spindash from the Sonic The Hedgehog series, the reason for this items creation is to add a land mobility item that could be of similar if not greater use to the end game item Elytra. I forgot to mention the measures of obtaining the item, you can get it by finding it in an chest (probably in a mountain.) And also bonking into walls will decrease Durability of the boots.
