I'm currently using five pairs of NB running shoes, three trail and two road. One of the road pair are the NB 1340 stability shoe. I love it. They are all sized 9.5 4E.<br /><br />I ordered the 1540V2 in the same size and it was marked as such in the shoe. It was clearly at least a 10. It was too long and there was no way to snug into the heel. I didn't get to test it much but it also seemed too stiff and heavy...everything that is great about the 1340 taken too far.
