My understanding of Lake's and my experience with Sidi lends me to believe the Sidi's are going to be a more narrow fit in the toe box, even with standard width Lake's. I just bought a new pair of road shoes, hence the recent research. I could be wrong, never tried Lake's, but I did look into them quite a bit. FWIW, I did my 1st ride with my new Bontrager's this morning and they definitely have more room in the toe box than the Sidi's. In retrospect, my Sidi's, from about 12 years or so ago, were probably a bit narrow for me, and I am a "standard", not a wide, in most sizing charts. Hope that helps a little.
