I used to wear Nike Free Runs.  Great shoes because I mostly lift and do cross fit oriented things (sprinting, indoor or track running).  I'm not a distance runner.  When I had to run distance (physical assessments, with friends, random 5k etc etc), these would be wonderful.  Never had any knee pain, ankle pain, or shin splints.  However, they have awful ankle support (avid racquetball player) and cost upwards of $100.

Enter these New balance shoes.  Gave the same feel of extreme light weight as the Nike Free Runs, but less floaty.  The sole on these is harder rubber as opposed to thick lightweight foam on the free runs.  This gets you closer to the ground, giving more ankle support and better ground feel.  Closeness to the ground is preferrable during olympic/power lifting. I use to have to shed my nike free's for heavy deads, now I don't have to with the New balances.

After about five months of serious wear and a lot of racquetball time, part of the sole has come off.  I super glued it back while I order more, but I can't say anything negative.  I abused these shoes and they worked great.
