I've been running for years.  After getting Achilles injuries off and on, I decided to go more natural.  I had done the Reebok flex shoes for about 6 months, which were nice, but these Skechers are are much flatter, and super light.  I will never go back  to high heeled running shoes again. I ran in these for about 5 or 6 months, until they had holes in them.  I then bought two more pair. I got an off color that were really cheap. They were on the NYC Marathon winner.  So, they will not hold you back.
