  • 35% efficiency: the ratio between energy released and energy stored
  • Articulated single axis ankle for good dorsi-plantarflexion
  • Mobility level K2 on the Amputee Mobility Predictor
  • Polyurethane injection molding
  • Forged stainless steel adapter, code 33.004.08.EXT
  • Sizes 22 to 29 cm sound limb foot length, left and right
  • Maximum user weight 100 kg (sizes 22-25) or 130 kg (sizes 26-29)
