AK Runner wrote a review of La Sportiva Fireblade Trail Running Shoe - Women's on May 31, 2012
I've been a runner for 26 years now and these are great running shoes. They are great on pavement and good on trails with a heel that's a bit lower to the ground. I've run in Montrail Hurricaine Ridge for years now, and though I like the support those have for roots and rocks on trails, these are an improvement over those because they are super light and fit like a glove. The soles are a bit thinner than the Montrails, though, so I do feel rocks and roots through them.
Definitely no rubbing, because the fit is comfy and great. Nice Job, La Sportiva.
