In reply to jolivague: I might be able to do it (Llanberis Resoles) but I would have to know the details. Which Inov8 soles lasts well(!) and what shoes do you want to fit them too?
Stripping an old sole off and putting it on to another shoe is also likely to have some issues, it would be quite different from putting a new sole on as they are normally larger and then trimmed to fit exactly after they're stuck on.
Best to get your friend to email the details. My address is on the website. Alternatively I'll be offering approach/fell running shoe resoles in Vibram's version of Dotty Stealth when the rubber arrives sometime in June.
Hope that is of some help.
