ABSTRACT:
Footwear which is versatilely useful for both land and water sports is described along with a method of production. A stretchable fabric vamp is conformable around the upper arch region of a user's foot. The vamp is joined to an upper edge of an elastomeric base piece including sole and fin portions. The flexibility of the vamp provides comfort and versatility for various walking, running, surfing or swimming activities. The base piece is more rigid than the vamp. The fin is stabilized by a toe support which contains the user's toes and is part of the same unitary base piece. The rigidity of the base piece provides hardness for the sole to protect the foot from harsh ground conditions and stiffness for the fin producing desirable water resistance qualities for enhancing swim power.
