Size is 41, but I have extra heel pad added to make it more snug for me.

The padding is approx. 0.5cm thick. You may be able to have this removed,
but that's not a guarantee as I never try to remove it.

I will guess it's probably fit more like a 40 with the heel pad on it.
But please see photo for full details.

Will double box it before shipping.
