Sidi is the world's bestselling brand of road shoes, and the Genius 5 Pro is the model that sells the most. Its Lorica upper has all the upsides of leather with none of the negatives. Lorica is supple, conforming, highly breathable, and will not stretch. In addition, Lorica is water repellent, highly abrasion resistant, easy to clean, and won't rot or dry out. Sidi combines Lorica with ballistic mesh to give you superb comfort, fit, and ventilation.The Genius 5 Pro Shoes are made with Sidi's Millennium 3 Carbon Composite sole. Unlike the nylon construction of the Millennium 2 sole, the Millennium 3 is constructed from injected carbon fiber in a nylon matrix. This provides 37% greater stiffness than the Millennium 2, and it's more durable to boot. One other nice detail with the Millennium 3 is its replaceable non-slip heel pad -- great for when you're click-clacking through Starbucks.Sidi adds a ratcheting buckle so you can micro-adjust strap pressure to ensure that the fit of your upper won't be too loose or too tight. It's mated to a Soft Arch Compression Strap that more evenly spreads the upward stroke pedaling forces across the top of your foot. The buckle provides 4 clicks per uptake along with half-click releases, meaning that you can precisely tension the pressure of the strap. No other system so precisely and so gently provides custom fit. You also get the precision of two High Security Velcro straps per shoe. The Velcro is reinforced with integrated locking teeth to absolutely, positively resist slippage. Combine these straps with a molded plastic heel cup and you end up with unmatched security. Its padded tongue with fit "relievers" is one final small (but important) detail that helps deliver unparalleled comfort. The Sidi Genius 5 Pro Shoes are available in White and come in most half and full sizes between 38 and 52 European.
Weaknesses: Costly, and you have to try to be sure about your size (the number is with a lot of approximation)

The carbon sole tansfer all your power to the pedals but, reduce the vibration.
