I have a pair of Saucony shoes that are over a year old, so I would say that they are broken in. On Sunday I was doing some volunteer work and was on my feet for over 5 hours and I noticed that the bottom of my toes were burning and my pinky toes were starting to form blisters. I was hoping that these shoes would be my saving grace when we go to Disney next year, but it looks like they might have stay behind. Has anyone had a simular problem? I have read the thread about "which shoes." Maybe I will try the Straprunners. BTW - I was wearing socks that had Cool Max in them.
