I've read a lot of comments and reviews...
I've read a lot of comments and reviews about touring boot and proper fitting, but i'm still confused about this:
What's the difference between size 29 and 29.5?
I think it's the same shell size. Does the thickness of liners is different. Or only boot sole thickness is different?
The answer will vary for different brands and sometimes models within a brand. The Zzeros have the same shell size in a 29.0 and a 29.5. The liner thickness will vary.
What does it mean " The liner thickness will vary"?
Since the shell size is the same for the 29.0 and 29.5, the 29.0 will have a thicker liner than the 29.5.
