Ah I did miss this! So when I put the Ghost 11 on vs the Ghost 10, the shoe just feels...better. In the 10 I thought the forefoot fit a bit funny, maybe a tad narrow(?). It doesn't feel super light but its no brick by all means. The 10 was also pretty durable too. The 11 feels a lot more free throughout the shoe. Meaning, the foot doesn't feel as constrained in the toebox. Another thing, the 11 feels lighter on foot. Personally, I really like the 11 over the 10. I know customers have really been digging the upgrade from the 10 to the 11 as well.
For me I would choose the 11 over the 10.
