Welcome to EpicSki. It is not obvious to me that these are anything but adult skis, other than the mention of "Raceflex Junior Plate." Whether they are or aren't is immaterial. These are not the skis for you. These are skis for someone with very advanced skills, well beyond what you no doubt have. There is no forgiveness is a ski like at all, make a mistake and the ski will punish you. If you need some help deciding on some potential skis, there are some questions that you need to answer and after doing that you will get some recommendations about skis to consider. You also need to be very realistic in assessing your skill level. Your preferences for blues and not going fast indicate to me that you're more intermediate than advanced. It is pretty difficult to become an advanced skier if you are always renting gear.
Also, more important than skis are the boots. Boots are the most important gear you can own for skiing, much more important than skis. Before even demoing any skis, you need to have boots that actually fit your feet, unlike rental boots that don't fit anyone's feet. Go to the "Ask the Boot Guys" forum and read the wikis about terminology and fitting, then check the "Who's Who" to see if there is a boot fitter near you. If there is make an appointment and go get fitted for boots. If not, tell us where you live and someone will be able to recommend a fitter. Do not go to a big box store like Sports Authority to get boots because anything you get there will be too big.
