I have a pair of joules they are lovely, durable and warm but I find the shoelace always finds its way to being undone somehow no matter how tight I tie it. I also have a pair of woof wear boots.... I love them, easy to pop on and off, good to ride in and good grip, mine have done a year with no leakage yet
I love my Woof Wear boots, they are so comfy but mine do let water in a bit when walking in long wet grass. I didn't realise they are only splashproof until after I'd bought them. So, so comfortable though and I just shove plastic bags inside in bad weather!!
I would love to have said Tyne Muckboots because I thought they were also awesome, until the heels split. I believe it's a fairly common problem sadly. Can't comment on the Joules ones.
