In reply to Lorenza-Lee Lockyer:
Take a look at Scarpa, la sportiva, Meindl, brasher, saloman. There's very good leather boots, and there's very good synthetic for all uses. So find something that will be comfortable. Sounds like 3/4 season boot is what you are after, provided you are just walking, and only want one boot. If doing lots of peat bog trotting ala kinder / bleak low / dart moor etc, the leather would be my preference.
