These have been on two trails and have close to 20 miles on them already.  They fit well and are super light.  I had a blister the first time but that's to be expected when breaking in new shoes.  2nd trail no issues and they are my new favorite shoes.  Loved the color too without even realizing it I matched my entire outfit with them on their first outing.  I went from heavy hiking boots to these and now I feel like I want to run those trails!
