Wayfaring Boots in Heroes 4

Hero gains +10 spell points, gains a 25% movement bonus, and ignores all terrain penalties. A hero wearing the Archmage’s Hat, the Staff of Disruption, the Wayfaring Boots, the Ring of Flares, and the Angelfeather Cloak is granted the ability to ignore an enemy hero’s or creature’s magic resistance.

When worn, these boots seem to make the wearer’s feet one with the ground allowing him to move quickly and tirelessly through the most difficult terrain.
