Sensible
Both the Brooks Trespass (reviewed in the latest RW) and the Adidas Supernova Trial have second density medial posts - on the inside edge of the midsole - to help control pronation. The Asics Gel Nandi from a couple of years ago was also a good shoe for the trail running looking for stability, and you might be able to pick up a pair from some of the retailers featured in the magazine or here on the website.
