Full size/Large poultice boot by Shires.
Only worn twice by my horse for approx 30mins in total while turned out in a small paddock.
Fitted my 16hh IDx with ease.
Some surface discolouration from the soil to the outside of the boot but no other damage.
Boot no longer required.
From smoke free home.
Collection from Little Budworth, Cheshire or I can post for £3.
