These shoes are very spacious and comfortable. When starting out your ride you can dial in the shoe to be as snug as you like. Then as the miles and day progresses and your feet swell you can easily reduce the tension with a quick squeeze of the boa.
Finally replaced my Performance shoes I bought about 12 years ago. Was able to buy these shoes. Long over due, to say the least. Such a great product. The fit and construction is so good. Tried some Shimano shoes, they just don't fit my feet. If you're going to do any cycling at a consistent level these are a really good option.
I've worn Sidi Genius road shoes for years. Now that my left foot metatarsal bone on little toe has grown outward, my regular shoes rub. I researched and found these Mega Road Shoes which are made wider. That's true. Wearing them gives me more room and no rub. But they are really larger. My normal size 43 seems almost too large for me. But they are very much Sidi quality and very usable. No rear foot adjustment. Good for the price, especially on sale.
