In reply to willworkforfoodjnr:
> I'm nearly 36! :p I also have a bad habit of both leg-crossing, and hanging my legs over the end of the sofa at home - I've stopped both (or I'm correcting when I notice!) and hopefully things will start to clear up
Is that the opinion of a medical professional? There's some very serious conditions that can cause an idiopathic drop foot, so if you haven't been properly checked out then maybe you should? An MRI scan is not uncommon to rule things out.
Re orthoses, I'm an orthotist, so you could try one of these:

They are very effective when it's just a foot lifting problem and the other muscle groups are intact. If there are other muscle groups affected then it may not be appropriate. Eg inability to do heel raises. I'm not fan of the orthosis in the first reply as it is a lot harder to adjust the tension to the correct amount and the design it pretty primitive in comparison. The ribbon that attaches to the shoe has a habit of stretching with time as well. There's a newer version, but I still don't think the design is as good as the Boxia.
