I really love the inov8 shoes, best barefoot shoes I've ever owned. The problem is the f195 kids where are out for me at about a hundred miles.  I walk 6 miles a day so I'm constantly find new pairs I have 3 in rotation at a time.  The version 2 of the shoe was absolutely horrible showing serious and significant wear after only about 50.  So happy that they brought back version 1.
