I have 2 pair of Specialized shoes - both 40s and I wear a 9 or 9.5 in street shoes. The Taho shoes seem to be similar in shape to the Rockhopper 04s I have. They are kind of wide in the toe box as opposed to my road shoes which are a little narrower. Given that I'd probably go with the smaller ones initially. Or you could order both and just plan on sending one set back.
