<p>A foam having a frequency of 10 Hz, a storage modulus of 1.7-2.5 MPa obtained from dynamic viscoelasticity at 25°C, and a tandelta of 0.01-0.14; a shoe sole member made of the foam; a shoe sole having the foam; and a shoe having the shoe sole. The foam has a sufficient strength and combines a suitable degree of elasticity and a high degree of rebound resilience.</p> |
