@Scienceofsport @Alson09130825 @SaraTetraDec@TimHutchings1@_MarcScott How do you propose WA better regulate footwear? If not the existing stack height rules which already are a farce when it comes to higher stack shoes slipping through the cracks and results getting recognised
@Scienceofsport @Alson09130825 @SaraTetraDec@TimHutchings1@_MarcScott Well if this is indeed the way it’s playing out in the real world, with bigger variation in response, then more onus on athletes to find what works best for them...
@Scienceofsport @Alson09130825 @SaraTetraDec@TimHutchings1@_MarcScott Shoes have always had an affect on performance and I would bet that there hve always been runners that respond to one shoe more than another pre 2017
@Scienceofsport @Alson09130825 @SaraTetraDec@TimHutchings1@_MarcScott Also never had the marketing hype seen w the 4% and subsequent studies + scrutiny. Previously companies bring out a shoe and don’t market it with an advertised study and name it after results of a study! Where was the study to promote the 1st shoe to have EVA!
@Scienceofsport @Alson09130825 @SaraTetraDec@TimHutchings1@_MarcScott Not sure we are in that different a place historically. Always been footwear innovation. Only difference now is possibly a bigger/ faster jumo in tech than previously. Ie the improvements in shoe tech in the last 3 years may have taken 10 years on previous trajectories
@Scienceofsport @Alson09130825 @SaraTetraDec@TimHutchings1@_MarcScott My point is we just don’t really know when it comes to the spikes and there was a hint that non- responders are possible in the most recent 4% study https://t.co/2PWVABfrAr
@Scienceofsport @Alson09130825 @SaraTetraDec@TimHutchings1@_MarcScott You’re basing your assumptions off the data from the 4%. The dragonfly only shares the same foam. It has different geometry, stack, drop and plate material and shape. No doubt there will be some ‘responders’ to these new spikes but the response may not be as big as you assume.
