I do a lot of walking and hiking and I found these shoes were easier to get used to than one would expect from reading the inserted tips from the manufacturer.  The shoes are very comfortable and I had no problem when I wore them for an entire day.  I did not feel any strain in my legs or my back.  The most noticeable effect in my experience is that they do improve my posture. I am 72 and have a tendency to walk a little hunched over, but not when wearing these shoes.  They make it comfortable to walk standing up straight.

One note I would add is that the shoes tend to run a little smaller than the indicated size.  I normally wear size 9 but my Skechers are quite snug at 9.5.
