My Muck boots are totally fxxxxx , had them years, they've never given good grip on wet grassy banks even though the chunky grip pattern looks impressive.
I'm liking the look of those Skellerup,s someone mentioned, never heard of them. I would never get foot ware mail order, but there is a stockist in Easingwold , about 40 mins away from me, may pop there next week.
I'm vary wary buying any footwear. A few years ago I bought some expensive wellies, possibly Barbour, can't remember, but .....
Brand new, took a walk around a local reservoir , they ripped my heals to bits. I took a tooth brush to the soles got every tiny bit of dirt off them and managed to return them for a refund. Hence I'm vary wary when buying new ones, especially if expensive.
