    Just the right fit.

    Euro brands have a reputation for cobbling slim, sculptured shoes that remain tantalizingly off-limits to cyclists not blessed with the delicate feet to match. Before you write off Euro brands completely, slide your foot into the Sidi Ergo 4 Carbon Mega Shoe and experience a slipper with expert European construction and a platform that actually accommodates your taller instep and wider-than-average forefoot.

    Sidi blends beloved features from throughout its line to create the Ergo 4, so if you're familiar with the brand, you're likely to recognize things like the Tecno 3 buckle system and Adjustable Heel Retention Device. The Tecno 3's dual ratcheting buckles provide micro-adjustability across the length of your foot for a contoured, secure fit that works for your foot. A wider platform shouldn't translate to a sloppy, loose fit, and Sidi unsurprisingly succeeds at striking a balance between the two with the Ergo 4. To match the heel of the shoe to your foot, tighten or loosen the adjustable heel to establish a secure fit that won't slip or waste power when you stretch out of the saddle mid-climb.

    Underneath, the full carbon composite sole handles power transfer, creating a rigid medium through which to transfer power from the engine to the frame. A full carbon shank surrounded by nylon-reinforced carbon achieves a balance of slight flex for comfort with uncompromising rigidity during punishing efforts.

    Love these shoes

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 45.5

    These are my first Sidi shoes and I'll never stray. These are the first cycling shoes that are actually comfortable right out of the box. I'm so impressed. These have great amount of room in the toe box and good volume. More importantly, they have arch support. Usually I have to buy a 46 and then add insoles to a shoe that never fits correctly. These are also hugely adjustable. I didn't experience any issues with the tongue and was dialed in by the end of my first ride. I have put 500+ miles on them since and absolutely love these shoes.

    Great for Regular-Wide Feet

    • Familiarity: I've put it through the wringer
    • Fit: Runs small

    I now have a couple of hundred miles on these shoes. The increased width of the Ergo is perfect for regular to wide feet. I tried the Wire Carbon but they were WAY too narrow!! Really well built shoe. I switched from a Specialized FACT Carbon. ORDER A FULL SIZE UP IN THESE SHOES! I wore a 46 in the Specialized. Ended up with a 47 in the Sidi Ergo. Only real issue is the serrated edge of the tongue. Sort of digs into the face of your ankle for the first couple of rides. Once it is broke in I didn't even notice it. Well worth the money in my opinion! Very satisfied.
