U'll prob have to pay slightly more than 30 quid if u want comfy wellies that will last. Depends wot ur using them for thou?
last few pairs i've had have been Nora's and before that Dunlops suregrip, usually get a couple of years out a pair wearing them all day every day for 8-9 months of a year. think there about 40-50 from agri/tractor shops.
The muck boots/buckler are quite good and warm, bit heavier thou.
I couldnae justify buying the expopensive wellies, my dad traeted himself to a pair a few years ago but rubbish really, never lasted
If u have cold feet buy 1 size bigger and get a pair of boot sox thingys, bloody great things absorb any moisture/sweat so ur socks stay bone dry
