Use pads until the sole hardens up and then re-evaluate...go through two or three shoing cycles. She may not need them permanently. I use them in this manner and have had good results. When a problem occurs, like an abscess or stone bruise, once everything has gone through the motions and the horse is sound again I pad through a few shoeings and then go without just to make sure the bruise/abscess issue has grown out, closed up (as in drainage hole for an abscess) or hardened up and then I re-evaluate.
During the winter months I am more prone to pad if the horse has had sensitivity before..more of a "just-in-case" type action.
