Not too sure what topic to put this under, I also posted this in the lounge, but I was looking into a bike fitting system called wobble naught and he mentions using a custom heat moldable inserts for the cycling shoes. I have researched a few and they are quite cheap. I notice that in the February edition of Runner's World, they also had these inserts. The #1 on their list was Archmolds (www.archmolds.com) Has anyone ever tried them, if so, did they help with increasing watage on the down stroke and what is the general feedback. I am interested in trying them I just want to understand what I am trying.
