I used these boots, for my silver D of E expedition and a three week expedition to Uganda. Throughout, they were strong, flexible and comfortable boots.
After walking for several days at a time I still want to keep wearing them; I have had near no blisters and rubbing, and I have yet to find a more waterproof boot. Although they come at a hefty price, they are definitely worth every penny.
They fit narrower feet perfectly leaving your feet ready to continue walking after a night's rest. I would strongly recommend this to anyone. Brilliant.
