Does anyone know if there a new version of this spike coming out with possibly updated specs. UA website has this shoe as 5.8 oz and in the question and answer area it is listed as EVA foam ( I did verify the weight and foam type with UA by chat). On Running Warehouse they list the weight as 4.5 oz and the mid sole as pellitized Pebax. I actually received a pair from them and the weight is closer to the 5.8 oz weight but the foam does look pelletized ( cant tell if it is pebax or not). I am wondering if Running Warehouse might have the specs for a new model that is coming out rather than the current version that they are actually selling.
