I have had nice luck running primarily in Saucony shoes the past few years. I brief foray using some racing flats (Nike)too much in training and too many hills has led to a chronic achilles tendonitis/tendonosis issue the past year. My podiatrist recommended that I go with a more structured, less flexible shoe than my more recent one (Kinvara). He recommended a couple of Asics shoes- the Nimbus was one, and I think the 2160 was the other but I am not sure off the top of my head. I tried a Nimbus for fit but was not sold on the fit. I typically wear a 15 and have found Saucony shoes to fit well. Can anyone recommend a Saucony shoe that may fit the bill?
