I have ridden Sidi's for the last 5 years. My first pair were Genius 5. I would rate them fair. These Genius 6.6 are excellent. They have addressed all the issues I had with the 5's. they are extremely well vented., they provide great side support where the 5's had none. The wide size fits my toe box perfectly without allowing me to swim in the rear of the shoe. This shoe actually fits American feet, not just Italian feet! I will keep buying these. 5 stars.
