@Jonathan Are you riding with the S-Works 6s or 7s?
A few years ago I tried the Giro high end lace version (forgot the name) and hated the fit so I settled on the Giro Trans (mid-level) which was (past tense) a great training shoe at the time (they’ve cheapened the Trans since). Note: I had used SIDIs for 15 years - too sloppy a toe box - better for wide feet which I presume that you don’t have if you have been riding with S-Works.
I wanted the BOA dial on both upper and lower so I was planning to try the Bontrager. However, several members of our cycling team (Alto Velo Racing Club) were using the S-Works and loved them and Bontrager hasn’t improved the design since they introduced their shoe in 2014. The 7s had just come out (last summer) so I read A LOT of reviews, including the improvements over the 6s.
From my very first use of the 7s back in August of last year, they are FANTASTIC!!! Literally no break in period an no issues such as complaints I have read about the 6s. They fit like a glove; power transfer is incredible. In speaking to Cognition Cyclery in MV where I bought them (a leading Specialized reseller in the Bay Area), the lady/cyclist told me that even her experience of moving from the 6s to the 7s was excellent (she has only been riding S-Works).
Bottom line recommendation: If you aren’t riding the 7s, you should give them a try.
