Här är några nyare test, där man inte testat skornas ränder, utan deras egenskaper.

The effect of three different levels of footwear stability on pain outcomes in women runners: a randomised control trial.
Abstract
BACKGROUND:
The present study examines the injury status in women runners who are randomised to receive a neutral, stability or motion control running shoe.
METHODS:
81 female runners were categorised into three different foot posture types (39 neutral, 30 pronated, 12 highly pronated) and randomly assigned a neutral, stability or motion control running shoe. Runners underwent baseline testing to record training history, as well as leg alignment, before commencing a 13-week half marathon training programme. Outcome measures included number of missed training days due to pain and three visual analogue scale (VAS) items for pain during rest, activities of daily living and with running.
RESULTS:
194 missed training days were reported by 32% of the running population with the stability shoe reporting the fewest missed days (51) and the motion control shoe (79) the most. There was a significant main effect (p<0.001) for footwear condition in both the neutral and pronated foot types: the motion control shoe reporting greater levels of pain in all three VAS items. In neutral feet, the neutral shoe reported greater values of pain while running than the stability shoe; in pronated feet, the stability shoe reported greater values of pain while running than the neutral shoe. No significant effects were reported for the highly pronated foot, although this was limited by an inadequate sample size.
CONCLUSION:
The findings of this study suggest that our current approach of prescribing in-shoe pronation control systems on the basis of foot type is overly simplistic and potentially injurious.

Injury reduction effectiveness of assigning running shoes based on plantar shape in Marine Corps basic training.
Abstract
BACKGROUND:
Shoe manufacturers market motion control, stability, and cushioned shoes for plantar shapes defined as low, normal, and high, respectively. This assignment procedure is presumed to reduce injuries by compensating for differences in running mechanics.
HYPOTHESIS:
Assigning running shoes based on plantar shape will not reduce injury risk in Marine Corps basic training.
STUDY DESIGN:
Randomized controlled clinical trial; Level of evidence, 1.
METHODS:
After foot examinations, Marine Corps recruits in an experimental group (E: 408 men, 314 women) were provided motion control, stability, or cushioned shoes for plantar shapes indicative of low, medium, or high arches, respectively. A control group (C: 432 men, 257 women) received a stability shoe regardless of plantar shape. Injuries during the 12 weeks of training were determined from outpatient visits obtained from the Defense Medical Surveillance System. Other known injury risk factors (eg, fitness, smoking, prior physical activity) were obtained from a questionnaire, existing databases, or the training units.
RESULTS:
Cox regression indicated little difference in injury risk between the E and C groups among men (hazard ratio [E/C] = 1.01; 95% confidence interval, 0.82-1.24) or women (hazard ratio [E/C] = 0.88; 95% confidence interval, 0.70-1.10).
CONCLUSION:
This prospective study demonstrated that assigning shoes based on the shape of the plantar foot surface had little influence on injuries even after considering other injury risk factors.

Ni som tycker att man skall löpträna i sockiplast, läs five fingers, får svar på tal här. Trot om ni vill, men det går åt mindre energi att löpa med ett par Nike Mayfly på fötterna än i strumplästen.
