judging a steel and aluminium shoe for horses

Question
Hello sir, how would a trainer say that a horse needs an aluminum shoe or a steel shoe??? How would you judge which kind of shoe to be shod to which horses???

Answer
HELLO HUGO...

Same questions as the last 5 questions ??!!?

A trainer would need to make the decision bye which if he/she needed more traction or not.
Steel will get smoother with wear. Aluminum grabs and bits the ground better, but wears faster. And is more expensive.

Also...aluminum keeps the horse lighter and many feel, moves a horse more natural.

Thank You...
