PodChatLive is a weekly video live stream that I co-host with Ian Griffiths on Facebook. After the live stream, its available on YouTube and our website. The audio version is also available as a podcast.

It all started when I was in the UK and visited with Ian and his family for dinner. After dinner, Ian set his phone and we went live on Facebook to have a discussion about whatever came up. When I returned we repeated it remotely. The following week we had on a guest (Chris Bishop) and it went from there. We now have a different guest or group of guests on each week and it is free to watch and will always remain so.

Why? We like the feedback, we like the positive comments. We do not charge for it and make no money from it, so all get from it is the positive reception that it gets.

Supination Resistance

Supination Resistance is another one of those topics that I find myself writing about a lot (eg here and here)and something I have been banging on about in my Clinical Biomechanics Boot Camps for years.That is how important I think that the concept is.

The concept has its origins in the concept of overpronation probably not be all that it is cranked up to be, so rather than focus on “overpronation” perhaps he focus should be on the forces that are associated with the function of the foot and pronation. It just makes a lot more intuitive sense o be focusing on the forces rather than the motions. It is the forces that actually do the damage to the tissues rather than motion. Motion is not painful.

I have certainly done a lot of research on it and unfortunately never quite got to publishing it. I did summarize most of the research done in this post.

Abductory Twist

This is something I find myself writing about a lot (here, here and here)

In a lot of those articles I refer to Kevin Kirby’s excellent video and you really can’t go past it for a description and an explanation:

It is a common finding, commonly associated with overpronation and also commonly confused with a medial heel whip. There is a lot of confusion between the abductory twist and the medial heel whip, especially in social media commentary. They are not the same thing. They are two very distinct and different phenomenon. The abductory twist is what is in the above video. A medial heel whip is something that occurs after the foot is off the ground.

I have actually given up responding in social media to those who are confused between the two. Move on.


This is something that I write about a lot and debate about a lot on social media. It is something that I do not like writing about. It is something that I should not have to write about. It is something that just will not go away. The myths keep on being perpetuated. It does get boring and tiresome.

‘Overpronation’ is a meaningless nonsensical term. It is mostly used by people suffering from the Dunning-Kruger effect who want to pretend that they know what they are talking about when they clearly have no clue. Pronation is normal. We have no idea what is “over” or abnormal. It used to be considered a big risk factor but it was so poorly defined that we really have no idea.

Over at Running Research Junkie, I wrote about:
‘Overpronation’ … the quack is strong in this one …
The nonsensical understanding of ‘overpronation’
Risk of Injury From ‘Pronation’

Over at Its a Foot Captain, I summarized it as Pronation Mythology and even posted about it on the company blog and laughed at memes on it.

One does get frustrated with not a day going by in which I come across someone talking about “overpronation” in a nonsensical way. When I get time, I will finish on the PodiaPaedia page on overpronation for a ‘fair and balanced; view (as that is the purpose of that website).

Please: it is time for all this to stop (though I know my pleas are not going to make any difference)
