This sub is not a serious place for barefoot running.
Everyone's favorite user on this sub (trevize1138) believes that the feet can never toughen up substantially. He believes that barefoot runners can never be fast; he gets a ton of upvotes for everything he says and posts; he writes long incorrect posts about running form when he clearly has absolutely no talent or knowledge of anatomy.
here's a comment from the moderator of the sub, it should tell you about the seriousness of this place with regards to barefooting:
My dirty little secret is I don't even run in minimalist shoes anymore
