My second pair of minimus running shoes - I also have the minimus trail shoes. I used to hate long distance running b/c my knees and back would always hurt. Then I decided to transition to 'barefoot' style, minimus running and got into using these minimus shoes - it's totally changed my whole approach to running and now my knees/back no longer hurt when I run.

As for the MR10 Road shoes, they are like running in slippers. There is adequate cushioning for the road or gym, and the lower heel drop ensures you land on your midfoot vs heel so you'll get closer to good form running. uppers are light and you can wear with or without socks. the only downside is the soles don't have a lot of traction so on wet surfaces can be a bit slippery.

>>Video Reviews: I have 4 detailed video rules on the new balance minimus line (including reviews about using the trail shoes for Tough Mudder and other mud races) - if you go on youtube and look on 'TheHelpfulDad' channel you can see the vid reviews.
