I was suffering from multiple problems as a beginner runner. I'm sure that my stride and foot strike were totally incorrect, but I also had shin splints, knee pain and hip discomfort. The first day on these new shoes, I shaved 15 seconds off a mile and from step one, have had no pain whatsoever. My shin splints are completely gone. Today I shaved off another minute or so from my mile (this was my 10th-ish run on them). My stride is more consistent and my feet don't hurt at all. I really love these shoes!
