Authentically Barefoot

Loyal reader Paul Olfert sends along the following:

 I was watching TV today and saw an infomercial advertising a new kind of insole for your shoes that replicates the feeling of being barefoot (and thereby solves a host of back and neck problems), the way "nature intended". I suppose "nature" also intended us to be riddled with ringworm and schistosomiasis and all the other diseases avoided by adequate footwear.
