What size ski do you have? How much do you weigh and how tall?
With the boat at speed, your water should break at the heel of your front foot while skiing flat (not turning, accelerating, etc). Given the proper length ski for your weight, your boots may be set up too far back. Was the ski new? Did you set up the bindings, fin, or wing?
If you search the web for ski setup, there are several tips which will help.
