The fit is ok, they are definitely a heel striking shoe only, they don't pivot/transfer well from heel strike to toe push off. The sides of the heel/ankle push outwards during this, and you lose support when pivoting from heel strike to toe push off. Overall they are incredibly clunky, I was excited because these shoes supposedly had even more cushioning than the original Ignite's (Which are truly a  great neutral running shoe), but extremely disappointed after running in these shoes for 3 weeks. They were so bad, I ended up giving them away as I knew I could not run in these. It blows my mind how different these feel as compared to the original ignite's. But if you're a heel striker, and you don't push the pace, below 7 minute training miles, these may be worth a look. But for midfoot or toe striker, you'll be extremely disappointed.
