  Ryan et al (1) provide empirical evidence that standards for running shoes in relation to foot posture are far from convincing. In particular, a sophisticated and expensive motion-control design intended for highly pronated feet was less effective than more basic shoes in minimizing injuries and pain to all categories of foot. This outcome echoes Richards et al's (2) recent negative review regarding the role of shoe design in reducing injury.

  I wrote a rapid response (3) to the latter paper suggesting that the origin of the conundrum may not reside only in biomechanics, but rather there may be a psychological element concerning the individual's interpretation of risk. The extreme form of this conceptualisation is "risk homeostasis", whereby it is argued that the individual "targets" a fixed level of perceived risk to govern his/her performance on any given activity (4,5). The psycholigical mechanisms by which risk is perceived and affects behaviour remain speculative; one model is based on low-level learning of the outcomes of competing tendencies in beviour (6). The typical activity to which the conceptualisation is applied has been road- travel and reflects the observation that may safety features do not maintain their benefit over time: drivers squander safety benefits in less careful driving, as reflected for example in greater and more erratic speeds. Two examples concern seat-belts and ABS brakes (5,6,7).

  As applied to running, the implication is that greater sophistication in shoe design reduces the perceived likelihood of potential injury; however, the consequence may be an increase in risky running behaviour. For example, the runner may pay more attention to uneven surfaces when wearing a less sophisticated design of shoe, but determine that a more sophisticated design deals adequately in equivalent circumstances; if this is not the case then more pain and injuries will result from the more sophisticated design.
