This item is crafted by Leatherworkers with a skill level of 300. The pattern is sold by Braeg Stoutbeard in Dalaran for 3x Heavy Borean Leather.

The components are:


 * 8x Heavy Borean Leather
 * 2x Eternal Fire
 * 2x Eternal Water
 * 4x Nerubian Chitin
 * 1x Frozen Orb

These boots give a lot of health and a good amount of frost resistance which helps for the Sapphiron encounter in Naxxramas. Although not an essential piece of kit, it is highly beneficial for mitigate damage from the frost aura effect.
