I have tried every major brand and style of running shoes and these are the best. I am 56 years old and have had multiple surgeries over the years for various reasons. These shoes provide the best stability and cushion regarding impact. I ordered a size 10 and 1/2 which fit like a size 10 in other shoes....so order accordingly. I worry that Brooks may discontinue this model someday and was thinking of stocking up! The second best shoe and my back up is an Asics model that closely matches this Brooks design, but doesn't provide as good of cushion for impacts. Anyway, that's my input. My motto, I don't run fast, but I do run.
