Bad luck Cheeks.
A good pair of thongs* is worth their weight in gold. They take on your character and, more importantly, the shape of your feet. Trust you find a new pair soon and that you and they have a long and happy relationship.
And another thing. I can't remember ever seeing thongs for sale in China. I can remember seeing some horrible hard plastic "things" that one tended to slip out of with each step one took, but I can't remember seeing thongs. Memory playing tricks with me or what?
*I know that the rest of the world calls 'em flip flops or something similar but, damn it, in Hoganland they are thongs and thongs they shall remain. Admittedly, this can lead to some confusion. As one website once had it "A crowd of Australians wearing thongs might not be quite as exciting as you would expect."
