I originally bought this model of NB shoe in my normal size of 10.5 4E, and found it to be too tight, lengthwise.  Since I have a relative who it did fit, I passed them on.  Buying the next size, 11 4E, I thought I would be safe, but was wrong - it did not fit.
I also own, and wear NB models CMW374, M992 and MR993, in size 10.5 4E.  They are made in the USA.  Both pair of MX608V3 I bought were made in Indonesia - relevant?  Are they real NB?
