Riding boots size 7, wide calf (Ware SG12 0)

Does anyone have any spare, old riding boots please?
Size 7 adult, wide calf.
My daughter has been voluntarily been helping out at local stables for several months and now has been given the opportunity to ride.
However, she cannot currently afford the cost of new boots.
Also, in need of some mucking out boots too, as hers now have holes in them!
Thank you for reading this.
