The Bloodbird offers superior stability in the mid-foot and shines in workouts with less dynamic movements such as weight training, where the focus is on grounding and stability. With a 55 shore EVA foam in the midsole, the Bloodbird is a solid choice for movements requiring attention to balance such as squats, deadlifts, push press, cleans and jerks. We believe that tough situations build strong people which is precisely why we built the Bloodbird.
