Like who would ever buy a pair of shoes that claim they could make you run 4% faster with the same effort.
Two pieces of super responsive foam either side of a carbon plate to maximise all your downward pressure into then moving forward.
Nike even backed there new super shoe by getting the worlds best marathon runner at the time, to run the fastest known marathon and break the 2 hour barrier. It was not classed as a world record because they also used rotating pacers to help him but either way it was still very impressive to watch somebody run that fast for that long. I really struggle to hold that pace for more than 100 metres yet alone 42 kilometres.
I held out for a long time thinking nobody wants to see an old age group jogger in flashy neon coloured shoes and funny heels trying to run fast. That would be almost as bad as being one of those older over weight guys wearing lycra on a super expensive time trial bicycles.
Unfortunately I got sucked into both by the magic of marketing. The shoes were just the hardest to resist, they were on sale at a direct factory outlet, I just had to see what all the hype was about and did they actually work. Would 2 pairs make me go twice as fast?
I can report that all the technology put into these shoes actually do work, They feel light, comfortable, soft, bouncy and responsive. Hard to calculate exactly how much faster I go in them but it definitely feels faster. Did I actually need them? Probably not! The cheapest shoes in the store are more than adequate to get me around my local parkrun course.
