Hi, Australia Calling.
Firstly I would seriously look at the option of Radiotherapy for the long haul. In late 07 I was treated by Prof Seegenschmiedt in Essen Germany for Ledderhose in both feet. During my discussion with the Prof. who is also a runner ,he advised me to use a cream on the feet regularly, even Vasoline. ( He applies a liberal amount before a run ) I use a cream containing a high potency 10% of Urea which is not as messy, and retains the moisture in the skin. The Prof. recommended the Urea cream ,applying it at night and wear light cotton socks.
I now look for shoes ,that have a good soft shock proof base ,which reduces the impact. When I was diagnosed, I went and saw a Podiatrist who recommended that I wear authordics and only wear lace up shoes. I was told I have high arches ,which can also place a large amount of extra stress ,when you suffer with Ledderhose.
Do you have knuckle pads on your hands, as about 40% of suffers of Ledderhose have knuckle pads , which I discovered when reading "Radiotherapy for Non-Malignant Disorders" by Seegenschmiedt.
Hope this helps. Regards.
