I have a neutral foot. These are pretty perfect. I have worn Asics for several years now and turned to the specific nimbus model a year ago. No complaints.

Overall

I’ve run in ‘ASICS shoes for many years and they have always performed very well. Primarily for me, they fit perfectly for my foot size and shape. I’ve used the entire 2000 series, but in recent years switched to the Nimbus model and they are terrific. Just the right amount of cushioning, neutral control, reasonable weight, and fine durability. Any time I have tried other shoes they did just not feel as comfortable.
