I previously had the NB 1001,1003 and 1004. Obviously I was happy with the product and the changes were at least consistent, if not always improvements. This new version is built on a different last so the fit was not the same at all, so just ordering my usual size did not result in the expected fit (felt bigger, or maybe the same width but longer? definitely not the same). The quality/stability also seemed lower than earlier models in this series, although the breathable mesh form of the shoe is still there are a big plus if you play in hot weather. Anyway, I had tried another wide tennis shoe that fit better and this one did not fit the same as the same size in the prior 3 models (to my surprise) so I returned this shoe, with good support from Amazon.
