Apart from, it appears, Welbeck, every other CCF have to find their own boots. We buy ours in bulk when the cadets join, along with a few other necessaries such as name tags, trouser twists and an OG T-shirt. With subs, it all comes to about a £50 initial joining fee.
We'd love to do it cheaper, but wheras you can pick up the odd few pairs of boots here and there, we're looking at 70-80 pairs each September!
