I had no problem adjusting to the Newton shoes. When I started I considered myself a midfoot runner. The shoes are amazingly light and comfortable, especially the racer shoes. Since transitioning to Newton shoes, I've notice improved results in all of my race distances from 5K to marathon to Ironman's. In addition, the shoes have kept me "injury free" (knock on wood) by teaching me to run with optimal form. The levers really do work and helps my legs turnover especially during those late stages of a race.
