Sidi is a great and iconic brand and I have used previous versions of Genius. But it's by far the most comfortable cycling shoe I've ever owned. I suspect it has a lot to do with the landing. The 42.5 (8 1/2) fits me like a glove with some welcome room in the toe box. I was new to the Double Techno-3 Push lacing mechanism. It takes a little getting used to, but once you get the hang of it, there's no turning back. The fine tuning is very nice. I use these Look Delta cleats on Look PP-396 pedals
