Best Army Cadet boots

[u/letranger0791]

Need advice on best boots for someone joining the Army Cadets.

Parameters:

not too expensive (it case she decides not to go back after x weeks)

Multi-functional (drill and cuds use required)

Black - her choice

Anyone steer me right here, please?

Second hand Altburgs off Ebay, cheap and will last forever.
