Another vote for the Aigle Parcours ISO. I thought they were a ridiculous price for wellies but it was lock down time and I bought them out of boredom, but after over 4 years of very frequent winter use (daily wanders in boggy water meadows and the like), they were worth every penny. I had a pair of neoprene lined Decathlons before (about £40 worth if I remember correctly) but I found them unsupportive and quite narrow under my feet.
To make the most of wellies, the fit is quite important as you don’t have the adjustability of lace ups. So if you can, try them on, and where there are size differences in the calf etc, try to get it right.
