Hello. These are generally designed for road-style shoes and some MTB shoes are a bit bulkier, which can affect the fit. We don't have any Shimano shoes handy here at the moment to test for you and they do make a few different styles too with different fits, of course, so I'm sorry that we can't specifically answer your fit question.
We're happy to help if you need assistance with returns or exchanges too so please let us know what questions you have: 1-800-783-8326 or firstname.lastname@example.org.
