Lighter riders won't mind the foam core unless of course you rip, and ski very aggresively. Its not so much the core that I didn't like about them, its just that I didn't like the overall ride. They were decent. 3 stars out of 5. But, if you ski powder often, don't weigh too much, and got a good deal on them, then more power to you, because odds are you will like the ski.
