Adidas Iniki fitting compared to the tubular radial

I wear a size 10 for the tubulars, but my feet are REALLY wide ( like a centimeter wider than regular sized feet i think). Should i go for a size up or down for the iniki?

(size 10 is the proper size for my feet length but i usually have to size up to accommodate for my width)

i had to wear size 11 for the pureboost clima if that helps for referencing
