Edit to my review of Aug 2011.  Amazon only allows one review per product.  Couldn't add additional reviews on my two new pair.  Used the edit method.

 Pair purchased in August 2011 from Amazon was white, made in China.  Subsequently  purchased another white pair, made in Indonesia.  This month, two more pair.  One black, one grey.  Total of four pair of MBT Sport 2s, purchased from Amazon.  Questioning the black pair.

I have suspicions the black pair may not be genuine.  I have now owned 5 pair of MBTs.  Due to high resoling costs, I replace them, rather than resole them.

My earlier white MBTs, and the new grey pair, are fine.  Both perfect stitching and color.  Both identical to my first ever MBTs, purchased at a high end retailer.

The black pair is made in China, and they have a cardboard type of feel.  The stitching is imperfect.  The colors on the MBT logo are faded, not crisp.  I lifted up the top section of the inside, and the markings were not the same.  Not marked MBT on the blue insole (blue when you lift it out).
Even though made it China, I would not expect that type of difference.  I would advise buyers to stick to the white or grey Sport 2s. Since I wanted a black pair for the muddy winters in OHIO, I will keep them.  The price is low, the shoes are wide enough, and cost the same as a cheap pair in a discount store.  My initial impression, after comparing it with the other two pair of MBTs, is that they are not genuine.  I will wear them, and update after continuous wear.  I do want to emphasize that I previously purchased/received a white pair of MBTs, that was made in China.  No problems with that pair

Below is my initial review from August 2011.  They are for the first white pair, that was made in China.

-----------------------------------------------------------------------------------------------

This is my second pair of MBTs.

I like these much better than my Skecher shape ups.  Better balance.

Wide toe on this model.  True to size.  Probably not good for a narrow foot.

Obviously, I like MBTs enough to get a 2nd pair.  My earlier model has been discontinued.

Items of concern.

My wife hates her MBTs because they are heavy.

Resoling is  $ 90, including shipping.  Ouch.  I am hard on my soles and mine must be resoled every 6 months.  Not a problem for other people I've spoken too.
My local shoemaker does it for $ 60, but it's not as complete a resoling as Resole America (MBT recommended vendor).
Google Resole America to check resoling cost for MBTs.

My earlier model was made in Vietnam.  These are made in China. A lot of complaints about MBTs made in China.  I took a chance.

My earlier hard sided MBTs are great in slush.  Heavy, a lot of shoe, and good for walks in slush.
Got them very muddy during a hike, and hosed them off without problems.  MBT says keep them dry.  Don't get them wet.

I wouldn't expect this softer sided model to tolerate getting wet very well.
