I've been wearing orthotics for about three years. I have a fallen arch on the right side only, and discovered this when I went to my GP. I was referred to an orthotist through the NHS ad recieved custom orthoses free gratis. My problem was that I thought that if I wore motion control shoes I would be fine, but spent the next year with knee trouble because the combination of both threw me out too far. I'm wearing a neutral shoe(pegasus) and everything has been fine since. Perhaps your husband can try the same angle on the NHS?
