I was apprehensive about buying these because a couple reviews said they were narrow but I'm glad I gave them a try. I overly pronate and have flat wide feet but these shoes cradle my foot so comfortably that I don't have any issue with the fit.  Normally my feet, knees & hips are so sore after a couple hours of walking but these shoes offered great support so my foot was in a more natural position (thus no knee & hip pain). The heel cup is extremely comfortable too. I've tried other brands like Orthoheel, New Balance etc...and find that ASICS is consistent in making a supportive - COMFORTABLE - shoe.
