I have recently started a diet and began daily walking about 3 months ago.  Every other shoe I have worn would cause a vast amount of discomfort after a while, which limited how far I could walk to a mile or so before the pain became to much.  My calf and shin muscles would get incredibly tight (Even with stretching before).

I tried these shoes after reading the reviews and they really made a difference in walking comfort.  I can now walk for miles without discomfort.  My muscles don't get near as tight.  Which makes stretching much more effective (and allows me to walk in other shoes without discomfort).  I still wear these most of the time,  but it's always nice to have options.

About the only complain I have, and it may be related to my size (about 265 lbs), is that the soles seem to wear quickly for me.  I have about 100 miles on my first pain (I bought more after trying them), and the sole is looking pretty rough.  I am guessing they will be only good for about 200-250 miles,  but that is just speculation.  I'll update when I get that far.

I highly recommend these.
