Snow angels

[Gothmog]

but what of those such as Elrond the half elven and his 3/4 elven children?

And what makes that question even more interesting is the Maia blood in Elrond. Can divine spirits like the maiar walk on snow? If they can, Elrond (being 1/16 maia, 3/8 man and 9/16 elf. Hope I got that right...) should have greater "snow-walking" abilities than Legolas. Or does the man-blood make him lose some of his skill?
