I have been happy with the Louis Garneau shoes I started with over 2 years ago, and I have a slightly wide foot with a bunion and arthritis in my big toe. However, they will need to be replaced in the next few months.
I got fitted by a Sidi representative yesterday after El Tour de Tucson. He said that Sidi's have a different cut in the toe box. I also have superfeet inserts in my current shoes, and he said that would add 1/2 size. So although my current shoes, are size 38, the Sidi's that fit me are size 39. The model I tried on was the Genius 5, but he said the fit would be the same on all of them.
They felt good overall, but I could feel a little bit of pressure on the bad toe- adjusting the velcro might be enough to fix that, but I'm not 100% sure.
I haven't decided if I can afford them but they gave me a 10% discount coupon at any local bike shop that carries Sidi, good until the end of the year.
