just getting into barefoot style running. due to an injury many years ago i'll probably never get into completely"barefoot" running but these shoes are close. very light, with very thin soles. the removable insole/sock made them fit perfectly. without it i think the shoes may be too large. but they add just the right amount of cushion for my feet so I am satisfied. these were a gift from my wife and now she also is interested in them. overall these shoes are great!
