I could be wrong but,the moulded soles seem to be a bit bigger in the toe area.
I got my Sidi chargers because they were alot flatter/narrower in toe area for gear changes.
The gaerne are "flatter" in the toe area compared to a few others I tried, so getting under a gear lever should be a bit easier. Gaerne don't import the enduro style sole in Oz. So I think I will be "slip sliding away"*
