M&S AirFlex Shoes Cracked Sole AGAIN!!

So after i chucked my last pair of Marks & Spencers AirFlex Shoes in the bin when the rubber soles cracked, letting in water and making my feet wet, i stupidly bought another pair.

Big Mistake - its taken less than one year of normal office wear for the replacement shoes to crack.

Do M&S know about this problem i wonder? maybe i'll post the cracked shoes back to them.

One thing's for sure, i wont be buying M&S Airflex shoes ever again!!
