Clarks — clarks (arista abe) size 5

Address:	110057
Website:	CLARKS SHOES

Dear sir/madam,
I been a die hard user of clarks footwear but my recent experience has been so disappointing and has left me so disheartened. I never expected such poor quality shoes from the house of clarks.
I purchased arista abe in nude colour size 5 and kept it for a special occasion but when i wore them yesterday for the first time this is what happened (*images attached).
There has to be a reasonable explanation for something like this to happen in a single use.
Kindly favour me with a reply.
Thank you!
