The Vibram FiveFingers Graspifier barefoot toe shoe pairs a thin, segmented sole with a stretchy synthetic upper that wraps the foot for a glove-like fit for weightlifting and gym training. The segments let the sole follow the foot's natural articulation, and the rubber adds traction for controlled foot placement. What Our Gearhead(R) Experts Are Saying:"Under a loaded barbell, the thin sole keeps my feet flat and low to the floor, so I feel the pressure move between heel and toes and correct my stance mid-lift."
