The beginning:
Running and Midsole Hardness
Introduction
Studies on midsole hardness of running shoes is crucial because of the simple fact that the quality of running shoes can directly affect the level of running performance as well as the likelihood of injury. Specific examinations within this article regarding impact forces were focused on the shock component in which running has an effect on both the running shoes as well as the foot. The focus on foot motion addressed the types of motions which are particular to running and how running shoes are able to interface with this intrinsic aspect. This article thus examined a set of crucial components of running, running shoes, and how midsole hardness is ultimate related.

The end:
.....hoe with hard soles has an additional cushioning function during running. But this ankle movement causes the inverting muscles to undergo a fast eccentric loading.
• During midstance, running with soft soles demonstrated a larger maximum
eversion and pronation, which in turn also load the same muscle group.
• The intraindividual differences were smaller than the interindividual differences. Although only 7 persons were tested, interindividual differences did come forward. A trend of general symmetry was presented. (De Wit, De Clerq, and Lenoir, 1995, p. 404).
Hard-soled shoes seem to actually offer more support and lend to faster running. However, the ankle movement may suffer undue impact. Softer-soled shoes were more suited for midstance.
