Abstract
A shoe member is formed of a polymer composition comprising (A) a composite material having a low molecular weight material retained in a medium material and (B) a polymer material. The low molecular weight material has a viscosity of up to 5.times.10.sup.5 centipoise at 100.degree. C. The difference in solubility parameter between the low molecular weight material and the medium material is up to 3.0. The weight ratio of low molecular weight material/medium material is at least 1.0. The difference in solubility parameter between the low molecular weight material and the polymer material is up to 4.0. The weight ratio of low molecular weight material/polymer material is at least 0.5. The polymer composition is enclosed in a rubbery or elastomeric cover particularly when it is used in the outsole.
