Familiarity: I've put it through the wringer
now.... that s the million $$$ question.... I have had SIDI for many years and absolutely love them. I ride about 12-15 hrs a week. So why try Diadora? Well, they are Italian also and they look pretty cool. Plus they were on sale. I wasn't a big fan of the boa lacing system, but I figure let's try it anyway. At the beginning they feel a bit strange and the dial/ratchet seems to put some pressure on your foot. However after hours of riding there is no pain developing where there seems to be pressure. Foot ventilation is far better on Diadora and riding in So. Cal this is a big deal for me. The boa does its job, no complains there. After about a month they fit like a glove. And yes I do prefer them to SIDI. This is why: all shoes come with crappy insoles including Diadora. So once you find the insoles you like or buy some custom made ones.... well good luck fitting them in your SIDI unless you go one or half a size bigger since their toe box is so small. (and I have thin feet) - Don't think that Diadora has a wide toe box, it is just a little more comfortable. Overall I like them better + nobody has them. Competitive Cyclist rocks!!!
