5 Month update: I don't notice the narrow tread when walking around on both dirt and on the pavement and haven't had any major slips. The lightweight nature of these shoes makes spinning feel easier. Pedaling the shoes with stiff soles helps more with the power transfer and I feel like I pedal more efficiently. They are surprisingly easy to wash with mild laundry detergent and water. In order to negate the narrowness, I slightly loosen the boa dials for a better feel. Overall I'm very much enjoying these shoes! My rating: 9/10 (minus 1 star for narrowness and slightly narrow tread).

Excellent video and with the foot sizing was really helpful 🙌

Excellent review with great information. Keep up the awesome videos!!

Hi thanks for you review. I like rx8 but the narrow tread seems unstable. But I like stiff. Are xc5 ok for gravel, hike bike? How is the stiffness? Thanks!

your 26.7 cm and went for size 44. Aren't they too big? From Shimano chart you should fit a 43.. I'm 27.7 cm and usually get a size 43. What should I order, size 45?!
