Further to my rant about my personal dislike of Swazi clothing, I have great pleasure in recommending Toggi wellingtons which I have been regularly wearing since moving to the Highlands in 2006,-(the same pair).
They are Toggi Wanderer Plus at about £70. Prior to moving here I had never done or had to do any serious walking in wellies, but conditions underfoot here often make them mandatory.
I know they are not the sexiest brand out there, but they are presentable in polite company and I bought them in Grahams of Inverness on their recommendation that they were a great favourite of local keepers. How right they were, and very reasonably priced.
I'm a 42 so I buy 44 and put a stiffening insole inside then a decent footbed, a thick pair (or 2 thinner) of socks. Does the job for me, and plenty of wear left.
There is a more expensive version with a full length zip called the Espirit if you've got fat calves!
