I had madams shoe's off because she cast one and the farrier didnt have time to put more on.
As a result, it was unplanned and she came out very very sore - for 4-6weeks. I actually think she had lami but it was masked by the shoes.
Luckily for us it was autumn, so we went into winter, she wasnt working as I didnt have any tack - so come october (2-3months post BF) she was sound and out hacking.
Grass is a problem for us - little -no grass and she has fab feet and 110% sound over everything - too much and she is footy. Its about finding where the balance lies for the horse.
For us, she was lame in shoes (tripped a lot) and the soundness when barefoot is worth the sacrifices in managment. If I couldnt keep her restricted, she would have shoes on.
Sometimes shoes in summer and BF in winter is a good compromise.
Last year we managed without boots, this year we have needed boots a lot but I think thats more a stiffness thing - she bounces with boots and pads, seems to really help with concussion.
