Yes - me.
Can't live without mine, have to wear them all the time, in all shoes, if I don't, I have chronic pain (crawling around the floor in agony-type). It's made a huge difference, but then I also make sure I take it slowly, stretch etc and if I feel any pain, then stop etc etc etc.
Very much down to skills of pod, I had a brilliant one to start, moved to another part of the country, was recommended to another one who was absolute rubbish and nearly caused me serious damage. I've now found another brilliant one who specialises in sports bio-mechanics, so I'm lucky - I trust her!
Mine are carbon-fibre, I've now got 2 pairs. The first pair are now 5 yrs old and were refurbished 2 months ago - I used to wear them all the time, but have now "relegated" them to ordinary shoes and have a new pair which stay permanently in my runners. My pod has recommended that I see her 1 x yr to have orthotics checked out, but she says no reason why I shouldn't get good few years out of them, as I have already.
Good luck, hope yours are as successful..........
