As seen half way down this page: http://www.altberg.co.uk/Web/military.jsp I've always used the older pattern "Boot, Combat, High" that are mainly unlined and therefore thin around the calf. They're also much higher in the leg than most Altberg offerings. My current pair have now developed a small hole inside near the heel in the lined portion - difficult to fix. I thought the Altberg Sneeker Boot might be similarly lightweight but still good enough for hill and dale. Any opinions?
