Muck Boot Tynes - what replaced them?

[AlltheFs]

My trusty old Muck Boot Tynes have died. I need something very similar that can be ridden in.
All the Muck Boots have changed name and couldn’t see which (if any) were for riding in.

What is the equivalent? Or alternative brand.

I loved my Muck boot Tynes there were brilliant boots warm and comfy for some I've had 3 pairs my first ones were the best for some reasons they don't seemed to have replicated them which is a shame I ended up with a pair of toggi riding boots and a pair of wellies

I book a pair of muck boot derbys from millets recently which I think look similar although a little shorter. The grubs rideline boots look similar too
