The effect of forefoot varus on the hip and knee and the effect of the hip and knee on forefoot supinatus …

…. say what? This study, that I will get to eventually, gives me the opportunity to address an issue I have been wanting to get to for a while, so the appearance of the research was timely. The issues surrounding forefoot varus and forefoot supinatus, even just not only on the terminology, but the diagnosis […]

‘Overpronation’ and running injury risk

‘Overpronation’ still continues to be misused and misunderstood all the way from the medical literature to the fan boys in the crankosphere blogosphere. For example, there was this study that got a lot of recent mileage in the mainstream media and the blogosphere that claimed to show that foot pronation was not associated with injury risk. It […]

It has gained widespread acceptance. Despite this, the definitive evidence supporting the concept is lacking; anecdotally a […]

Rearfoot and Midfoot/Forefoot Impacts in Habitually Shod Runners

When comparing the biomechanics of different foot strike patterns, these reseachers set out to answer the somewhat ambiguous question of whether the biomechanical differences are due to changes in footwear, foot strike, or a combination of the two: Rearfoot and Midfoot/Forefoot Impacts in Habitually Shod Runners Boyer, Elizabeth R.; Rooney, Brandon D.; Derrick, Timothy R. Medicine […]

Another look at the performance claims by the Airia One running shoe; a theoretical context

A few days ago I wrote about the launch of a new “biomechanically perfect” running shoe, the Airia One that made claims re enhancing performance. I won’t relitigate the issues raised previously, as you can read them here. The post engendered quite a response on Twitter, Facebook and in the blogosphere. One little dig that […]

The concept of ‘Supination Resistance’

For some time now the link between ‘overpronation’ and overuse injury has been known to be tenuous, but the most recent evidence does suggest that there is a small, but statistically significant risk for injury (but then that depends on how you want to spin that evidence and actually define what ‘overpronation’ even is, but […]
