i can't think of anyone who stores their skis by laying them horizontally. and if i'm asking about a wall rack to hang my skis from then i obviously don't have anywhere else to put them, let alone lay them on the floor hahahah

Just hammer in some thin nails or panel pins into the wall spaced the right width apart. Like for a pair of 180 skis that has a 120/100/120 sidecut you'd have two pairs of nails about 180cm high with each pair 115mm apart (probably will need a little experimenting to get it just right). Then just hook the skis onto the wall individually. Would be perfect for behind a door.
