Constructed to provide comfort and support even after miles of wear, the Ultra Run Crew features cushioned terry throughout the foot and toes, to help soften the impact of tough runs and workouts on feet. Each toe is separated, eliminating all skin-on-skin contact between toes and preventing blisters. The Ultra Run Crew, hitting at mid-calf, also features a ribbed knit throughout the leg for a tighter, more ergonomic fit.
