Shoes, from black to white

[vandt]

Hi

I have these shoes, they are black, but I want to change them into white..

I have read another thread, but I can't make them look real. It looks like they are glowing.. I have tryed to inverte colours, and used layer masks.. I have tryed luminosity, colour overlay.. But I have failed

Can anybody help me?

The picture is cropped, because the girl doesn't want to be published on the internet..

it isnt impossible there are numerous ways you could do it like how you said for example but then add a hue saturation adjustment layer or even a brightness\contrast layer and tweak it using the mask from the 1 you have created.
This is not perfect but if you work on it a bit then you can see it is possible,

The result looks best if the picture is black/white..
Hoogle thanks for the advice with the contrast/brightness adjustment layer..
