Though I have only had these boots for three weeks I have worn them every day in wet and arduous terrain. They are lightweight and robust with great ankle support and grip.
The lace locking capability at the ankle is very useful when adjusting for fit and the velcro support strap ensures security around the foot. They are a little inflexible at first, but took only a couple of days to become very flexible. The sizing does come a little small - I am usually a 6UK and needed a 6.5UK.
