THE SHORT ANSWER
The Adizero Boston 11 replaced the Boston 10 in September 2022 at $160, $20 more. It was an upper-only update: a thinner nylon mesh cut most of an ounce, while the firm Lightstrike midsole the complaints were about carried over untouched.

Stay on your shoe, or switch?
Faithful successorAn upper-only update that kept everything the loyalists were grieving. The firm Lightstrike midsole carried over untouched, so Doctors of Running was still writing that the Boston 11 needs to be softer, and Believe in the Run was still calling the ride blockish and bricky, now at $160. Faithful to the 10, which was exactly the problem.
Stick with the Adizero Boston 10 if
- The 10's softer mesh fit your foot; the 11's nylon upper is stiffer and runs long
- Heel lockdown is already marginal for you in the 10
- Discounted 10s undercut the 11 by $40 or more
Move to the Adizero Boston 11 if
- You want the same ride with most of an ounce gone
- The 10's forefoot hold felt sloppy at pace
- You pile on miles; the 11 is a 400-mile shoe

What loyalists said about the update
Quietly received: redditrecs aggregates only nine reviews for it, and its fans self-identify as contrarians ('I loved the 11s which everybody hated'). They liked it for real reasons, 400-plus-mile durability and a stable ride for bigger runners. The complaints were a 30 to 50 mile break-in and a cluster of foam-junction defects at the ball of the foot that ended in warranty claims.
