Never really had a bad pair of Clarks and thankfully none have disintegrated so far. Having said that you might want to take a look at GentlemenPreferBrogus.They are closing down as far as I know. Have bought 3 pairs of all leather shoes for £66 plus £3.45 postage. Fantastic shoes. Will intermix with my Clarks. Have about 50 pairs plus now lol. I like my shoes. https://www.gentlemen-prefer-brogues.co.uk/
As shown on BBC Watchdog 28 November 2018 when Watchdog reported on problems with disintegrating Clarks shoes.
