Yeah mine have fallen apart. 5 years I got but my cheapo rubber dunlops are still going.

The soles detached, rubbers split in multiple places no longer water tight at all..

Comfort and warmth was amazing just disappointed in durability I mean they are, or look like, they are bomb proof but I’ve never had wellies fall apart so much.

The le chamu I wore on the estate were like 3rd hand and several seasons in, the sole had worn thin but was still water proof. Probably my next pair tbh
