Abstract (en)
[origin: EP0092366A1] A pair of running shoes (20) each of which has a midsole (36) which, at least in the heel region, is made of two layers (40, 42) with complementary tapers across the width of the sole to provide a horizontal upper surface (46) when the lower surface (48) is horizontal. The two layers are of different durometers, the tapers and durometers being so selected that the ratio of the thickness of higher durometer to lower durometer material is greatest adjacent the inner or varus side (26) of the sole. This construction lessens abnormal pronation of the foot as the arch flattens during running and increases contact surface area, thus distributing impact shock more evenly.
