How is your skiing? With the new skiis it should have been a bit easier. The pain you are feeling is from skiing out of balance.
Tommorrow, when you get your boots on, look at the soles, there is a mark about mid arch. Next look at the skiis, and where the binding is set up, again a small mark, Those are the sweet spots of your skiis. When you ski, try to keep your balance on these sweet spots.
An exercise that may help goes like this:
After getting your gear on, to stand on the flat area of the slope, and with skiis on, jump up in the air, (small jump), do this several times, after the 2nd or 3rd time, get ready to do it, but don't leave the ground. This is the most athletic stance you can be in, and the best body position for skiing. Notice the sensation of your arch against the bottom of your boot? If properly mounted, your weight is on the sweet spot of the boot, and ultimately on the sweet spot of the ski.
When you get back on the hill, ski slowly, and look for that same feeling of compressing the arch to the bottom of the boot. You will notice it will conmbine bending at the hip, knee and ankle to create that sensation. Just as in the little jumps you did, you need flexation at those 3 points (hip,ankle, knee).
