I purchased these shoes to replace my previous Caterpillar work boots that lasted me nearly 2 years before the front tread of the shoe wore down to nothing.  I've had these ones now for nearly a month and they too have been wearing pretty well from a wear and tear standpoint, but I've yet to have them "adjust" to my feet.  They aren't uncomfortable, but most shoes would have conformed to a person's feet by this time.  I use these as work shoes, where I am outside, walking and driving for most of my shift.  The shoes still have a firmness to them, both the inner soles and the lace-up area.  I hope they will soften up in time, but as of this writing they haven't and that is why they are getting 4 stars.
