  • the mid ⁇ foot region 5 of the sole does not therefore need to support the user's foot across the full width of the sole 2, but only along the lateral side of the mid-foot region 5. This means that the weight and the cost of the sole 2 can be reduced by using less material in the mid-foot region 5.
  • the soles of the invention achieve the reduction whilst maintaining a normal plan view outline of the uppermost surface of the midsole, by reducing the width of the midsole from it uppermost surface to its lowermost surface such that the width of the uppermost is greater than the width of the lowermost surface, as described above.
  • Width in this context is defined as the distance across the sole from the lateral side to the medial side in a direction perpendicular to a longest line joining the tip of the frontal/toe region 4 to the tip of the heel region 6; shown as line 33 in figure 5.
