A removable ball of the foot insert for placement into footwear at a
position in correspondence with a forefoot portion of the footwear
includes a substantially planar member made from a viscoelastic gel, the
planar member including a lower surface and an upper surface, and a
plurality of spring walls formed from a viscoelastic gel and extending
from the lower surface of the planar member at a predetermined area
corresponding to a ball of the foot when the insert is inserted into the
footwear, for separating bones of second and third metatarsals of the
foot, the spring walls having heights that generally decrease outwardly
from a center of the predetermined area, and the viscoelastic gel of the
planar member having a hardness greater than a hardness of the
viscoelastic gel of the spring walls.
