Love the shoes - they are great for cycling. However, the size is wide. I wear a US size 9.5 or EU size 42. However, in this shoe I needed a EU size 45, 3 sizes bigger than I usually wear. Also, the shoes are narrow which fits me as I have a narrow foot but might not fit someone with a wide foot. Please note that the shoes do not come with SPD or other spikes, which need to be purchased and installed on the shoes separately.
