Bont are outstanding as a stiff racing shoes. There are also heat moldable, so you can really fine tune the fit. But they are stiff…
I’ve had great success with Sidi’s as well, but the width can vary somewhat between models. I have the original Drako’s, still one of my favorites, and the newer Drako 2’s. Both fit wider than the Sidi Tiger’s.
I like to use custom insoles with the Sidi’s, as the stock insoles offer little arch support. There are a few different brands that have worked well. Giro’s Supernatural insoles were great and have different wedges that you can put in. I think they stopped selling them though but I had heard they may bring them back.
