aluminium instead of a steel shoe

Question
hello sir, why to use an aluminium shoe instead of a steel shoe???

Answer
HI ALUMINUM SHOES ARE USED FOR LIGHTNESS AND RACING AND STEEL SHOES ARE USED FOR HEAVY TRAINING AND KEEPING THE FOOT FROM SPREADING TOO MUCH.SOME TRAINERS WILL RACE THEIR HORSES IN STEEL RACING PLATES FOR A MORE RUGGED AND LONG LASTING RACING SHOE. SOME OTHER TRAINERS WILL ONLY RACE IN ALUMINUM SHOES. THANKS ED HESS
