Trigger,
I have a pair, got them from the Expo - Sweatshop was doing them.
I previously have had my gait measured by two different companies (not sweatshop) and been told that I was a neutral runner. All O.K until I got Sciatica and just before London got Shin splints. Went to this facility which they told me that I overpronate and I came out £40.00 lighter but with insoles. I didn't run London with them and had a bad day.
Since then I put the insoles in my neutral trainers and shin splints totally gone and now just have a slight pain with the Sciatica. Everything's been fine using the insoles.
The insoles helped me out a lot initially, Sweatshop told me to go back in six months because your gait can change using them? - but nearest shop is over 50 miles away, so have decided on trying out stability shoes.
