I bought these 1340 v3 NB shoes because I have others and they are great for running. I love the look of them so thought I'd leave the reservation and give them a try. My previous shoes were 1260 v6 and 1260 v7. I thought a higher number would probably be ok. To my surprise, however, these shoes were rock solid. There's enough room inside, but they were so stiff my legs ached after walking the dog around the block and I could feel blisters popping up. So for me I would say NO to these shoes.
