Loafer- Your bases are probably a sintered base. They have become oxidized. I just looked it up in my manual which I received during a Toko waxing clinic I attended. Here's an excerpt from my book:
It is often incorrectly assumed that the modern sinter bases do not need waxing.The contrary is true, however, as these bases get brittle very fast and start to oxidize without wax.
The hard wax suggestion at the edges sounds like a good idea. In the East I understand you tend to get a lot of cold snow and ice.
The lower the temperature of the snow the more friction there is. lower temp=higher friction.
There are many kinds of snow. New, artificial, marbled, old, and wet. Decisive factors for optimum gliding are:
1-skier, 2-ski, 3-running surface, 4-wax, 5-struture, 6-edges, 7-snow/weather conditions.
Get your skis reground and ask the shop to put a fine structure not a course structure if you are skiing in cold snow or icey conditions.
I wrote an article on how to wax and tune your skis. It discusses the basics since there is so much to this art. Using just the basics I discuss in this article I had at least 3 or 4 guys ask me what the hell I did to my skis one day(since we all came off a run at the same speed onto a flat trail back to the lodge and I was passing them up at about 5 mph, not polling or skating... and they were!) and I said, "E-mail me and I'll tell ya." email@example.com
If anyone wants this article, e-mail me. Then send back your suggestions on what to do in certain conditions of weather and snow, or any special tricks you have learned. The more I learn, the more I can share with others, and the more gooderer I be.
