1. An insole for a shoe, said insole comprising: a body made of one of thermoplastic and thermosetting foam synthetic resin, said body including a heel area and a forefoot area having a top surface and a bottom surface, two recesses defined by said body located on one of the top surface and the bottom surface of said body, one of said two recesses being located at said heel area of said body and being spaced from the sides of said body, the other of said two recesses being located at a forefoot area of said body and extending laterally to opposed side edges of said body, two reslient members having a different durometer hardness than that of said body, said two resilient members being complementary in shape to said two recesses for frictionally engaging said two recesses, and said body includes a projection spaced from the peripheral edge of said one of said two recesses and projecting into said one recess, the resilient member complementary in shape to said one of said two recesses defines a hole frictionally engaging said projection, said body also includes two wedges, each wedge extending from opposed lateral edges of said other of said two recesses and the resilient member complementary in shape to said other of said two recesses defining two notches frictionally engaging said two wedges. 2. An insole as described in claim 1, wherein said two resilient members are one of several pairs of resilient members, each pair of resilient members having different elasticity and hardness than another pair of resilient members for changing the properties of the insole according to its use. 3. An insole as described in claim 1, wherein said body includes a projection spaced from the peripheral edge of said one recess and projecting into said one recess, the resilient member complementary in shape to said one recess defining a hole frictionally engaging said projection. 4. An insole as described in claim 1, wherein said body includes two wedges, each wedge extending from opposed lateral edges of said other recess and the resilient member complementary in shape to said other recess defining two notches frictionally engaging said two wedges.
