I'm looking at getting some new shoes this year and have narrowed it down too these two . I have riden in Sidi's for the last 15 years and love them, but am willing to try the Shimano's I have a wide foot so that's why I am thinking of the Spider, it has a little more room in the toe box , and the Shimano comes in a E and has custom footbed's Any feed back on either of these would be helpful.
