Could well be a marketing ploy, I can only go off the state of my own runners, I do 90% on cement so my soles are toast well before I get to 300 miles!dunno about changing shoes so frequently maybe just cynical but sounds like a marketing ploy been running for over 40 years, and normally just run on them until they fall to bits or the grip gets too poor for the mud in the hills even then if it is just the sole I would try and use them when the ground is dry and hard in the summer if we get any decent weather lol
