Iron Boots
The Iron Boots is one of the essential items Link will acquire on his quest after taking on Mayor Bo in a sumo wrestling match in a attempt to find a way past the Gorons of Death Mountain.
This item when worn will make Link very heavy allowing him to sink underwater and even assists Link in stopping the mighty Gorons rolling down the mountain preventing passage to the Goron Mines.
When underwater Link cannot breathe that long and will eventually drown if he does not eventually surface to regain oxygen although this issue is removed once the hero dawns the 
Zora Armor.
The most unique property of this item is being magnetic which is heavily emphasized in the Goron Mines were Link can attach himself on top of magnetic surfaces to walk up and down walls defying gravity.
Link can even put on the boots in mid air to help him sink faster or land into a magnetic field sucking him towards the surface.
The items primary use is heavily featured in the Goron Mines being the only item that can even help Link get past the first room among also being the only item in conjunction with a
sword that can help the hero defeat Fyrus the possessed patriarch Chief Darbus.
The boots are also used frequently at City in the Sky were it pulls down heavy switches in conjunction with the 
Clawshot something done to defeat the dragon Argorok terrorizing the Oocca.
