I would hesitate to say that all New Balance runs narrow, it really depends on the last that is used as well as the materials used in construction. On the WT909OR, the combination of our SL-1 last and the TPU on the toe creates a fuller fitting toe box. This is great for toe splay as well as swelling when running. If you have "really narrow feet" as you mentioned, I would recommend tracking these down in a 2A width instead. I think this would come closer to providing you with the proper fit for which I am sure that you are looking. Backcountry should be able to order them from New Balance if they are not in stock. - Bryan Gothie, NB Product Manager - Outdoor

New Balance runs narrow ALWAYS....I have wider feet and can never even come close to wearing New Balance ANYTHING...so I would think they are made for you!
