real problem here is that several studies have shown that the shoes improve performance by 4.5%. that is about 5 minutes or so. if that is true it has to be clear to everyone that the recent times, while real, are not comparable to times even 2 years ago. what happens now is very unclear. also, it may well be that based on running gait the shoes may help one athelete over another. so common sense dicates taking all these time (like dubai last night) and refrain from thinking that it is training or altitude or ... so i do not know where to rank kipchoge, probably after bekele , geb, kipsang, and kimetto for sure as he would be almost 2-3 minutes slower than each of them.
From what I've read, Bekele doesn't like the 4% shoes.
