After a dozen years and many thousands of miles my original Sidis were worn out, so I checked out the current marketplace in the $250 price range and found nothing sufficiently compelling to switch to. I ordered Sidi's Genius 7 Magnum, which suits riders with feet that are wide relative to their length. (See comparison photo.)

When my new Genius 7s arrived, complete with comprehensive user guide (a rarity these days), I inspected them closely and marveled that such an intricate piece of footware could be bought for only $250. Especially considering their origin -- Italian shoes are considered the best in the world and priced accordingly.

To an old-time Sidi wearer, the new Genius 7 is reassuringly familiar and yet completely modern. The design that has powered uncounted pro racers had yet to be improved on -- though I realize lace-up shoes are currently in fashion. But I'm not interested in fashion.

I tried them on and instantly found them more comfortable than my originals -- I hadn't realized the old shoes were pinching my feet until I wore these new, wider Magnums.

I fitted my new Shimano SPD-SL cleats (not wishing to desecrate my new shoes with ancient, worn cleats from my old pair), using the 10 mm bolts recommended by the vendor for Sidi shoes. The 10 mm bolts screwed in perfectly.

Then I took out my Specialized SL2 and went for a short spin up the 3.5-mile warmup hill behind my place in the Oakland hills. The efficiency of the originals is enhanced by the carbon sole. Power transfer to the pedals is optimal, and the new shoes do not pinch or bind anywhere -- they are more comfortable than my old shoes. (After long rides, I couldn't wait to get out of my old, too-narrow shoes. I doubt I'll be having that problem with these Magnums.)

So to sum up: the Genius 7 is a worthy descendant of the Sidis that became the standard of the sport. A beautiful shoe to behold, it simply resonates with quality and sophistication, without being the least bit flashy. And it's an efficient shoe for sport riding. My only wish is that these shoes were a little lighter.

I've attached a photo of a new Genius 7 Magnum and beside it, also in size 45, one of my original Sidis. Though the Magnum looks a size bigger, it is not too big for me -- the extra width is what I needed and it delivers.
