I bought these last minute before a trip to Disney World. My daughter told me that I was crazy and that my feet would be a mess because I didn't break them in first. I had NO blisters (first time ever!) very minimal foot pain after walking 10 + miles every day for 9 days! I'm not a runner, I'm overweight, middle aged and with these shoes I didn't feel like I was! I was the energizer bunny!
