    Genius 7 Carbon Mega Cycling Shoe

    It's hard to overstate the reputation Sidi shoes have earned over the past few decades, earning a cult-like following throughout the peloton and amongst self-sponsored cyclists alike. Built with extra circulation-saving space to free your toes from the confines of regular-width shoes, the Genius Fit Carbon Mega Shoe is the stuff of dreams for wide-hoofed cyclist. Stock up on a few pairs of these to keep cramped toes and pressure points a thing of the past on your road rides.

    The Genius Fit Carbon closes with Sidi's beloved ratcheting buckle system and two hook-and-loop straps, giving you freedom to make minute adjustments along your instep and working with a plush Soft Arch Compression Strap to prevent numbness and pressure from interrupting your pedal stroke. Sidi uppers are known for being some of the toughest of all, so throw any amount of rain, humidity, and road grit at the Technomicro synthetic uppers and be prepared to wait years before you see any significant signs of wear. Sidi balances their durability with well-placed mesh vents along the uppers, which prevent the inside of the shoe from resembling the walls of a greenhouse during hot rides. Finally, Sidi rounds out the Genius Fit with its Millennium 4 Carbon Composite outsole. The rigid platform will energetically deliver power from your legs to your frame, refusing to flex even when you're throwing watts onto the pedals at the end of a climb.

    • 1 ratcheting buckle and 2 hook-and-loop strap closure

    Good for wide feet

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 46.5
    • Height: 6'4"
    • Weight: 190lbs

    I have medium wide feet and wear size 12 in sneakers. I ordered 46.5 and they are a hair wider than what I would consider to be perfect, but I like them better than standard width road shoes.

    Excellent shoes..

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: 45
    • Height: 5'10"
    • Weight: 205lbs

    Retired, I ride 250-400 road miles a week and have been riding for over 35 years. I never knew Sidi had a wide or "mega" shoe and having wide feet, didn't think I could wear Sidi shoes. I've only got about a 1,000 miles so far but I love these shoes. Good fit, for me, and excellent build quality. Highly recommended.

    Tongue painfully rubs ankle

    • Familiarity: I returned this product before using it
    • Fit: True to size
    • Size Bought: 43.5
    • Height: 6'0"
    • Weight: 165lbs

    This review causes me trouble. First, the shoe itself is fantastic, well made, stiff. My issue is the same with this shoe as with many other shoes. The leather tongue rubs the front of my ankle. Any time my foot is at less than a 90 degree angle, it digs into my ankle. This is painful and if I ride more than a couple of miles it would undoubtedly cut through the skin (maybe just rub it raw through the sock). I really wanted to love this shoe. Rather than try to cut the tongue or figure out some other way to modify this expensive shoe, back it goes. And back I go to tri-shoes. What is with the freaking tongues on cycling shoes??

    Also, the wide sizing is absolutely perfect. I wear 9.5 in Brooks running shoes and have feet wide in the toe box. Cycling shoes are notoriously narrow, but these in the mega size 43.5 were a perfect fit.

    I had the same issue with the tongue cutting into my ankle. I solved problem by folding the top (1/8th inch or so) of the tongue back toward toe of shoe. After a couple weeks of riding, the problem went away.

    mega means mega

    • Familiarity: I've used it several times
    • Fit: Runs large
    • Size Bought: 46.5 mega (wide)
    • Height: 6'1"
    • Weight: 220lbs

    This is my first pair of Sidi genius mega's. I have a wide (EE) foot but a relatively normal size heel. The Sidi 7 fits perfectly in the heel and midfoot but is very roomy in the forefoot. I have had to compensate by wearing 2 pairs of socks which has cured the problem. I noticed someone mentioning stretch. They do need to be adjusted during longer rides. On the very plus side is the power transfer due to the stiff sole. Noticed a gain of 0.5 - 1 mph just with the change of foot wear.

    Great fit.

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: 42 Mega
    • Height: 5'7"
    • Weight: 158lbs

    This is my third pair of Sidi Genius shoes, my previous pair also mega size actually stretched until almost unusable, now I've used them over
    many years. The new ones fit just right and I'm counting on the new material they are now using will hold its form and not stretch as
    advertised . Great fit and comfortable.

    Material not as supple as earlier models

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 44.0

    This is my 3rd pair of Sidi Mega Genius and I admit that the outer material is not as supple as on the earlier versions I have worn. The material still is stiff after months of wear and should have that broken-in feel by now.

    Dedicated Sidi wearer

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 43 Mega

    I've worn Sidi Genius Mega shoes almost exclusively for the past 15+ years. Prior to that? I wore Sidi Genius regular fit shoes ... essentially, I've been wearing Genius shoes since the original buckle, the original sole, and since they only had one Velcro strap. I don't think it gets much more dedicated than that.

    Light, stiff, and form fitting, no shoe has ever fit my feet as well, which is why I keep replacing older Genius shoes with newer ones.

    My only quibble? The insoles are almost nonexistent. As I've gotten older and my arches have collapsed, I need more a little more underfoot support inside the shoe, so I've had to start using aftermarket insoles.

    That said, I've still never found another shoe with an upper that better conforms to the shape of my feet or that cups my heel as well with no slip. Since the way a cycling shoe's upper fits is just as important what's underfoot, it's going to take something amazing to convince me to change.

    Wide Sidi shoes

    • Fit: True to size
    • Size Bought: 42 wide
    • Height: 5'8"
    • Weight: 150lbs

    For someone with EE wide feet wide shoes are very appropriate for me and these work perfectly, especially after rides of longer than 2 hours.
