For the fortunate.

When it comes to fit that feels virtually molded to a cyclist's body, Assos definitely knows the score. For cycling shoes with carbon soles that can literally be molded to a cyclist's feet, Lake pretty much wrote the book. Combine the two, and you have what may be the most luxurious cycling shoes we've ever had the misfortune of testing and then having to give back: the Assos CyclingSlipper Shoes.

Though the power-to-the-pedals fit of the CFC race last is important, it's ultimately useless if the sole yields to input like nylon. Lake's expertise comes into play here, with the CyclingSlippers featuring the same carbon sole as Lake's top-end CX402 shoes. Like the CX402, the CyclingSlippers' soles are also moldable, for a crystal-slipper fit that wasn't initially manufactured for your foot, but that definitely fits it like a glove. Or a slipper. Or a CyclingSlipper.

The CyclingSlippers' Kangaroo leather uppers are soft and infinitely adaptable, conforming over the course of a short break-in period to the cyclist's foot. After they're imprinted with a given user's pedi-DNA, the uppers are almost as customized as the soles. The lining is both breathable and antimicrobial, and the heel and tongue liner demonstrates the Assos touch by actually regulating foot temperature. The shoes are finished with the ubiquitous-for-a-reason Boa wire buckles, which effect a quick fit before the ride and a low profile throughout it.

As good as it gets

I first saw these at a granfondo in the Assos truck. I tried them on, and really liked that the carbon sole extended around the heel, which felt very stable and good for power transfer. Assos actually offered a pretty good deal on them, which I subsequently wished I had taken. Fast forward several weeks, during which I dealt with some serious delay on a pair of Vittoria shoes I had already bought at a huge discount from Europe. A CC rep told me that the Lake CX402 shoe is virtually the same as the Slipper at a lower price so I bought the Lakes. They were definitely not the same shoe - felt and fit much bigger and bulkier than the Assos, and the quality was not of a $500 shoe - so I returned them, and decided to just get the Assos.

The shoes have a slightly bulky look to them from the top compared to Sidis for example, but look quite "slim" from the side. The carbon sole wrapping around the heel makes the shoe very profiled from the back.

The shoes are probably best for narrow to medium width feet. The toe box is quite generous, but the midfoot, and especially the backfoot, are rather narrow. That part of the sole is moldable, but I'm not sure whether it would widen enough to accommodate very wide feet. My pair fit me perfectly right out of the box so I have not messed with "cooking" them in the oven.

The shoes are very stiff, which is great for power transfer, but can make the shoe a bit uncomfortable when unclipping at a red light and putting your body weight on it since the sides are made of carbon. I believe some of the internet reviews I have seen complaining about the shoe being uncomfortable have something to do with the fact that the sole wraps around half of the foot. I personally certainly feel the shoes are supremely comfortable.

The boa closure system is the best I have ever used. I finally got the Vittoria La Tecnica shoes also with a boa closure system, and the Assos' closure is far superior to the Vittoria's.

Cons: the leather around the ankles had yellowed for some reason. It's a pure cosmetic gripe, not functional, but it certainly warrants criticism for a $500 shoe.

Verdict: Top of the line shoe that's as good as it gets in terms if looks, functionality, and technology. If you can afford it, you won't regret it.

Best cycling shoe I've ever had. Easy to get on and and get off. A really comfortable shoe, from the first time I put them on. Can't say enough good things about them. Just perfect!

Can someone tell me the "32" additional features that adorn these that the normal 402 does not have? The Assos literature states that there are 32 specific features after making sure they point out that Lake is no longer an American company.

WHO CARES!! THEY ARE $600!! SEND ASSOS A MESSAGE: YOU GUYS ARE INSANE!! IT'S A SHOE! THERE IS NO WAY THE MATERIALS, RESEARCH, MANUFACTURING ARE EVER GOING TO BE NEAR THIS PRICE POINT! STOP DRINKING THE KOOL-AID!

I don't know about 32, but the closure system is somewhat different, that's for sure. The Slippers also fit me better, look slimmer than the Lakes, which looked like loaves of bread, and are better quality than the Lakes. The sole does appear to be the same, however.

Do these come in a Speedplay edition?
