Been running in these for about three to four months now. I did quite a bit of research before I purchased them and it paid off.

My running surface is compacted dirt roads with a lot of loose rocks and 3/4" gravel. My normal running shoes are Nike Free 3.0. I love those shoes but can't use them right now b/c of the terrain. Lots of rocks were getting stuck in the splits of the sole and the padding was too soft and thin so I was getting bruises on the bottom of my feet from the rocks.

Enter the Kinvara TR. Low profile just like my Free 3.0's but a nice firm outsole to protect my feet from the terrain.

Fit: my normal running shoe size is 12D but a 11.5 is a good fit in these

Best for: trail roads with gravel, rocks, or other rough terrain.

Pros:
mud doesn't get stuck in the treads (awesome!)
sole is firm enough to protect from rocks but flex enough to be comfortable
minimal break-in required
dries fast
well constructed
many color choices

Cons:
None for now

Just ordered a second pair, half size smaller, to wear casually.
