Reports of injuries occurring while running these shoes, which are now manufactured by Brooks, Asic’s and others, have athletes second-guessing the value of the technology while turning to training the lower leg instead for strength and durability. Paula Radcliffe said on her podcast that the growing pain in her ankle during the Tokyo Marathon landed her in a wheelchair before the finish line. She was wearing Nike’s Alphafly 4s.
