This is the most stability I have found in any shoe currently available. Off-centre heel strike due to odd angled heel cutout. The shoe hugs my foot with every step. This won't bother you if you land on your midfoot, but I'm a walker so I hit my heel hard most of the time. Some of the new NB shoes, you need to order according to your foot size, but that's normal. Shoe sizes, so order your foot size plus half. Most consumers will say that this is "normal". I would also like to emphasize the large heel width. When you wear orthopedic insoles, there is a lot of room in the heel. It is currently HARD TO FIND in running shoes. Lately ASICS has frustrated me everywhere when it comes to customizing orthotics to fit a wide heel.
