I almost never visit this forum but read some reviews regarding the Propulse 3 and some users switching from the trusty Nike Breathe Frees to the Propulse shoes. I have been a loyal fan of the Breathe Free series for years, but now that they dropped the warranty, I run through them too quickly to keep buying them. The Nike Courtballistec shoes just aren't comfortable for my foot type, and it's the only shoe with a warranty in the Nike line. The vapor is such a comfortable shoe, but it lasts 3-4 weeks at best. I'm hoping the Propulse are as good as many of you say because I just ordered the red ones. I've got the foot type many said it was good for...wide and flat. I want to thank everyone for the contributions about all the different shoes. It really helped me make a decision this time.
