Shimano RC903 Wide Road Shoes

Answer of Alfred

These are too narrow for my feet

Answer of Andreas

The width of the foot varies under load, and it's not the easiest thing to measure. If your foot is 10cm wide with a lot of weight on it, size 41 wide should fit (my own feet are like that). If it's 10cm without weight on it, try them out, but you might need a shoe with a wider last, e.g. from Bont. Buying a larger size is usually not recommended. The shoe can get too long and the cleat adjustment range would be compromised towards the rear.

According to Shimano's size chart, a 47 is 29.8cm long, while the next larger size is a 48 with 30.5cm. Just 2mm longer than the foot might not be enough - a bike fitter recommended adding 8mm, Canyon recommend an extra 4mm. My guess is that size 48 will be more comfortable, but to be sure it's best to try both sizes.

Answer of Andreas

I can't tell you how much wider they are exactly, but it sounds like you need a wider shoe and this is a good one to try. Trying shoes is the best way to find a well-fitting one, unless you have a good bike fitter that can help to speed up the process. If you are careful and tape the sole, e.g. with bike frame protection tape, you can do a test ride without leaving a trace. Personally, I wore an S Works 7 before, which is said to be wider than the 902. I also had pain in the toes after a few hours. Now with the 903 Wide, I am much more comfortable.

Answer of Arkaitz

They will be wide, of course. But on hot days you will be especially grateful. Your case is exactly what happened to me and this summer my feet finally didn´t hurt. At first it will seem strange but then you get used to it.

Van a ser anchas, lógicamente. Pero el día de calor sobre todo lo agradecerás, tu caso es justo lo que me pasaba a mi y este verano por fin no me han dolido los pies. Al principio se te hará raro pero luego te acostumbras.

Answer of DAVID

Hello, they are 5% wider. It seems little but in reality it is easily felt. Too wide for me in any case.

Bonjour, elles sont plus large de 5% . Ca semble peu mais en réalité cela se ressent aisément. Trop large pour moi en tout cas.

Answer of Christian

My feet 271mm width 102mm, Rc 903 45 wide. 44.5 would have been enough the width does not bother me because easily adjustable. For 260 x 105 I think 43 wide should be suitable the 44 will probably be a little big and 43.5 certainly not available.

Mes pieds 271mm largeur 102mm, Rc 903 45 wide. 44,5 aurais été suffisant la largeur ne me gêne pas car facilement réglable. Pour 260 x 105 je pense que 43 wide devrait convenir le 44 sera sans doute un peu grand et 43,5 certainement pas disponible.

Answer of Arkaitz

Try the 43 Wide, of all of them it is better if they fit you more snugly than too big.

Prueba con el 43 Wide, de todos es mejor que te queden más bien justas que grandes.

Answer of Mariusz

I have a foot 26.8 left and 26.6 right and I had size 43 and it was ok, I had 43.5 and they were too big.

Ja mam stope 26.8 lewy i 26.6 prawy i mialem rozmiar 43 i byl ok mialem 43,5 i byly za duze.

Answer of Michael

My foot is the exact same size - 10.5cm wide and 26.5cm long. I bought RC903 in a 43 Wide and the fit is great - it is roomy and the boa locks my foot nicely. This shoe feels great after hours on the bike - all day comfort!

Answer of Arkaitz

Well, Wide in the head and I wear a 44 on the street and here I had to get a 43.

Pues Wide de cabeza y yo uso en calle un 44 y aquí me he tenido que pillar un 43.

Answer of Emile

It is still preferable to order larger for this type of shoe.

Il est quand même préférable de commander plus grand pour ce type de chaussure.

Answer of Jan

These are normal sizes yes, but the wide version, if you don´t have narrow feet...

Dit zijn normale maten ja, maar de wide versie, als je niet smale voeten hebt..

Answer of Liroy

They are normal sizes, they have a wide fit unlike other brands, very comfortable, they fit perfectly, I totally recommend them. For aesthetics, very pretty, white with blue iridescent color.

Son tallas normales, es de horma ancha a diferencia de otras marcas, muy cómodas, quedan a la perfección, las recomiendo totalmente. Por estética, muy lindas, blancas con color tornasol azul.
