After a recent cadre, when my feet where torn to bits by my Magnums, I've decided to buy a pair of Altberg boots. The problem is which pair? They have many different varieties, with different 'options' (waterproof lining etc.). I'm in Richmond (the factory) in a week, so any advice would be gratefully accepted. I'm on a training year next year, so they'll be used mainly in the field (Europe), although when in base I work behind a desk.
