A fellow Irish poster also not happy with LL Minsterm
it has failed in the back of one of my size twos which was, like yours, barely worn (maybe 3-5 times). Definitely something wring with it even if they won't admit it. Wondering if they can be fixed at all.
Thanks for the pm Rox. Wonder if it is more than the label they have changed though. While talking (emailing) Vicky at LL she me mentioned something about the elastic supplier. Could be wrong though!
