Did a tab over Brecon today in these boots and they are brilliant. (First time i have worn them 'in the field'. My feet got absolutely soaked but the boots remained comfortable and warm. I would highly recommend these boots for someone who doesn't want heavy gore-tex lined boots. See www.altberg.co.uk for more details. PS Before anyone comments on bad drills, the reason that the inside of the boots got wet was that the water from my soaking trousers ran off them into the top of my boot!
