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.
