I just received these today, did not buy thru Amazon but another online merchant.  I visited an MBT retailer yesterday and tried on MBTs for the first time, they felt great.  However they did not have the EMA in stock and I needed it for a cruise.  I ordered 39.75 size as I wear a size 9 and they fit perfectly.  I have narrow feet but I can wear these without socks or with thin socks.  The manufacturer's web photo currently shows these with a toe thong, but the ones I received today did not have that.  The EMA is very stylish, the sole appears a bit thinner than the old models, therefore I would feel comfortable wearing this as a dress shoe.  Still getting used to the rocking horse motion, but based on all the reviews I have read, this shoe should be great for my lower back pain, and my chronic foot pain following multiple foot surgeries.
