White's Boots are great. They are all leather and custom made to your feet, so they fit very well. The company will rebuild them too, for a price of course. I have a pair of their hiking boots that are a couple of years old, so I haven't had to have them rebuilt. They are rugged and provide a great deal of support, which is important to me since I have one ankle that occassionally gives me problems from old injuries.
They are rather heavy. There are lighter boots out there that use synthetic materials, but for ankle support and durability White's can't be beat.
No affiliation to the company other than being a satisfied customer.
