I had a pair snd they fell to bits after a month, since then I have bought cheap wellies which have lasted twice as long!!! I may have had a rogue pair but I wouldn't waste money on another pair.
I must be lucky, I am on my second winter with mine, and they are still lovely and warm and waterproof. So far they are lasting far longer than my last pair of second rate Hunters.
Worn mine a couple of months and I have splits and leaks all over mine I emailed caldene who said go back to store but they won't help without a receipt. Very disappointing.
