I have not tried this shoe. I doubt I will since I've read repeatedly how narrow the toe box is. The shoe is 5.8oz, $125, removable sock liner, and includes a 3mm heel raise pad. I'm NOT a fan of the lugs under the forefoot. Newton has a comical origin where the applied for a patent for lugs under heel+forefoot and they were rejected - so they removed the heel lugs and said it's a "new way to run". I can't find that patent submission, but here's Newton's springy heel patent. (Who it's bad.) There's a nice extended review of the MV2 here at runblogger.
Try this shoe on before you buy, seems like you need to size-up for proper fit!
Quote from runblogger: In summary, the MV2 is an extremely light, zero drop shoe that will
appeal to both Newton fans and those looking for a flat shoe that
retains a bit of midsole underfoot. The lugs are not as noticeable as
those on other Newton shoes, and the fact that they extend to the edges
on each side is a big design improvement. I suspect that this shoe will
retain the excellent durability of other Newton shoes, and thus may
outperform many EVA based racing flats in this regard. Minimalist
runners who prefer a wide toebox will probably not enjoy the feel of
this shoe, but if you are accustomed to running in racing flats or XC
spikes then this shoe will feel fine.
The Newton MV2 is set to be released in September 2011, and the MSRP is $125. They are currently available for pre-order on the Newton Running Website.
