The VJ Ultra 3 is designed for ultra-running and long training days where comfort and stability must hold up for many hours. The thick SuperFOAMance midsole provides softer and more responsive cushioning than its predecessor, while a RockPlate protects the foot from sharp rocks. The Fitlock construction keeps the midfoot stable, and the pronounced rocker helps ensure a smooth transition through each stride. The Superior Contact outsole is designed for secure traction on wet and technical Nordic terrain.
