I just switched from NB 1080 to the 1260 v2. The first run in the 1260 I notice a burn in the metatarsals or balls of the foot in the middle area. It almost tingled when I took my shoes off. I do have some inserts but they don't go all the way out to the toes. I only ran for about 30 minutes. Otherwise they were fine. Does this mean these are the wrong shoes or can I buy some inserts that cover the metatarsal area to prevent this?
