I would disagree with Kinkyboots in his description of the Altberg Defender boots, having just bought a pair myself. They are an excellent walking boot and give excellent ankle support. Ive walked over a hundred miles in them, several 20 milers across peat bogs, muddy fields, and streams. Believe me they are waterproof. Altberg discribe them as being just as waterproof as Sympatex lined boots, especially if cared for correctly. I would describe them as a 3-4 season boot, weather wise that is. May be too warm for summer use.
