For a while there some early research suggesting super shoes were increasing navicular stress fractures

In March of 2022, I developed a navicular stress fracture on my left foot after a bout of wearing Nike alphaflys for four races (3 5ks, 1 10k) and wearing Saucony Endorphin Speed 3's for every long run. At the time I thought it was simply because I overtrained, but when I further analyzed the lead-up to my injury, the training did not seem intense enough to cause such a devastating fracture. Nothing had changed in my form, diet, or stress levels. It wasn't until I recovered around 6 months later and finally raced in my alphaflys again did I realize exactly what caused it. After my race I experienced a very similar pain in my navicular bone on my left foot that I had only ever felt after wearing the alphaflys. Since then, I still race in them, but not very often. When I do race in them, I get that same feeling for about a day or two.

If super shoes caused more injuries we would know that by now.

My uncle got a stress fracture after I started wearing them, hence super shoes cause avuncular stress fractures.
