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!
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.
