Strengths: I've been running in the NB 763/4/5/6/7/8/9 and the replacement model did not really suit me with too much support. I bought a pair of the 1260v2 and went for my first run last week. The best word to describe them is "plush". They have the typical New Balance fit that I have been searching for, snug without being tight. I am a C/D width fitting so these are just right. The support and cushioning are just ideal and I cannot praise these shoes highly enough. I have had help from the really nice people at New Balance UK and they have gone over the top to look after me. Chapeau.
Weaknesses: They are not cheap!
Overall: I think it's the rekindling of a love affair.
