I wouldn't wear these running or outdoors. Most of the sole is EVA foam and wouldn't hold up for an extended period. These are made for indoor cross-training use, not running. I own many pair of NB Minimus shoes and you can't go wrong.

Pro's:
- great fit
- plenty of room in the toe box
- 4mm drop is great
- just the right amount of cushioning
- best without socks as they have an internal liner

Con's:
- Don't like the EVA sole. Will not hold up outdoors if you intend to run or walk in them
- Don't like the padded heel cup
