Hi,

How do these size up vs the racier Shimano offerings and their winter boots?

My 45 winterboots are perfect but my 45 M123 ever so slightly big. But still fine with a sock thicker than say a SockGuy sock. If that makes sense.

Cheers

Answering my own post…

Tried a 44 and 45.

The 44s are spot as they come up a little wider than “normal” Shimano MTB shoes.

If you have previously gone up a size to get a bit of extra width in shimano shoes you don’t need to with the AM45.
