As far as I know that data has not
Nike Air Max 90 Homme been published, so details regarding the testing are lacking. Was the difference statistically significant? Not sure. Did individual responses vary (e.g., by gender, body weight, running style, etc.)? No idea. What was the weight of the shoes? Don’t know. The latter point is important because if the shoe was the Energy Boost model which is reported at about 9-10oz, then simply wearing a lighter shoe that doesn’t cost $150 would seem to accomplish the same benefit. We know from existing research that we gain about 1% in economy from every three or
Nike Air Vapormax Donne so ounces we drop in shoe weight, so a six ounce flat might provide the same benefit. One could argue that the benefit of Boost is that you get the same economy benefit as a lighter shoe but with greater cushioning and durability, which may in fact be true, but then we get into the
Nike Air Max 2016 Donne question of how the midsole affects running form and the forces applied to the legs and feet. “When you try out the Adidas Energy Boost, don’t imagine that you’ll bounce effortlessly off the road or run as fast as Haile Gebrselassie. Instead, run in the store or on the nearby sidewalk and ask yourself: Does this shoe feel like a natural extension of my body? Does it feel like it was almost custom-designed for my feet? Does
Nike Air Max 90 Donne Nero it give me a smooth, crisp “ride” when I run in it?”In other words, don’t buy because of the marketing. Buy based on how a shoe
Adidas ZX Flux Womens feels on your feet. Try it on and run in it. Does it disappear, does it work with your stride, or do you feel like you fight the shoe with every step? These are the tests we runners need to apply.I think you’re being a little too dismissive of the mechanical tests. I agree that, in general,
Nike Air Max 270 Femme mechanical testing might not correlate perfectly with increased performance. However, because there are so many additional variables that are introduced when you switch over to physiological testing, it’s going to be difficult to get any sort of significant, meaningful data.I’m sure that shock attenuation is not the only important material property to test (e.g. does the contact time increase in boost shoes? springs have great shock attenuation, but each step would take 5 seconds), but I think in the long run I’d choose to compare shoes based
Nike Air Presto Womens on several different materials properties (whose results would be much more reliable) rather than seeing a percent or 2 difference in oxygen consumption in humans.This debate will continue until runners actually try the Boost. I agree it’s how it feels first and foremost. The marketing is the marketing and the ball test is trying to make a point in a simple fashion, to sell shoes to lots of people. Is the bounce a valid indicator of a runner’s energy return? who knows till we try them and real testing is done. What is interesting is that this is a new midsole material with very promising properties. In addition to the bounce effect the consistent cushion over a wide temperature range is very interesting. has anyone looked at the effect of temperature, especially colder temperatures on shoes and performance, those “brick”
Nike Air Odyssey Hombre midsoles on a cold day. Apart from Newton, trying to do a similar rebound effect by loading the lugs into the midsole then releasing or ON with their crushable lugs which spring back most everything else is more or less the same EVA and different geometries of midsole (stack height, drop, rockers, etc…). Lest we forget what has happened in use of new materials and processes above the midsole in just the last few years. These days hardly any decent shoe have stitched uppers, all welded overlays or no overlays at all Flyknit. Lighter less constricting shoes the result. Innovation is good and the Boost midsole appears to me innovative, due to the RW tests, if over hyped. I am getting a pair and will let you know. Now give me a Boost Adios or something with lower drop and I will be really psyched
