DON LAWRIE, USPTA: Lauderhill, FL-Head Pro, West Wind Park; Director, Broward County Grand Prix League:  "I'm on my feet almost all day long teaching, checking matches, or stringing racquets...but with the SPS Ultra Luxury Orthotics, I no longer have shin splint throbbing or fatigue at end of day...they help to maintain my footwork and stamina---especially with the advanced junior players. Another bonus is the comfort these inserts provide."
