Nick O.wrote a review of Giro Chamber Cycling Shoe - Men's on August 5, 2018
I will say they are not true to size. I wear a 10.5 on all my shoes and the 44 size is too small. Had to order another pair in 45 which should be just right. Not a knock on the brand as others who have reviewed stated that they are true to size. I just disagree with my experience. Anyways I’d buy 1 size larger just to take precaution. Nothing worse than a shoe that is too small and tight.
