These ornately embroidered boots are crafted by Varki artisans to help their hunters and warriors as they cross back and forth over the snow and ice of their homelands. Empowered by the magic woven into them, these boots enable their wearer to ignore any uneven ground or difficult terrain caused by snow and ice. Additionally, while Striding on ice, you can move 10 feet for every 5 feet of movement you spend, as icy blades grow from the boots.
