The Freestyle Swim Foot
from Freedom Innovations enables the user to go from walking to swimming quickly, and is designed to balance the body for a more efficient swimming technique. For those wanting to gain more speed when in the water it can be used with a flipper, thereby decreasing the amount of energy expenditure.
Users can go from walking to getting in the pool by means of a single push of a button, which moves the ankle from a 10mm heel height setting for walking, to 70° plantar flexion for swimming. For additional protection it comes with a cosmetic foot shell and a protective rubber cap that is snapped over the ankle to protect the system.
