I hadn't noticed that one at first glance. The subtitle (there's more
than one, depending on the edition) is "How We Got Skis." You can see
one edition of that here - you have to scroll to the bottom:

The one I remember had a different cover that showed the king on skis
jumping overhead. It has 60 pages. I remember it as a funny fairy tale
with plenty of realism to it - there's a serious food shortage in a
Scandinavian kingdom and an elf comes to the king promising to help
out - if he'll give up his son. (When the elf first arrives, he
magically lights up the palace because there's a candle shortage as
well and the king is doing his part to save on supplies.) The king is
given "magic" shoes - skis, of course - and the king has to learn to
use them and come up with the idea of making ski poles as well. He
manages to bring back loads of wheat - in that case, magic IS
involved, since he has no other means of carrying them - and as it
turns out, his son comes back, as the elf always intended. The elf
also sends a pair of skis for everyone, but the children, bolder than
their parents, learn how to use them first. The story ends with the
king, his wife and son deciding what to call the "magic shoes."
