I am exactly 10 in for my shoe size. (9.5 for Canada/us) I get a size 41 eur and a 42 CN. They fit me perfectly and in the photos it shows it. This red color was a bit brighter than anticipated, but I am enjoying it nonetheless. These red pointed stilettos are hot shoes and I love the fact that they have black bottoms, not too many red stilettos half the black bottoms. They are very sturdy shoes and do not feel wobbly as I'm walking.
