Where would i buy a spare zip thingy?

[HarderThanYouThink]

Strange question i know but i want to fix my sandals rather than buy a new pair (cant afford to) the zip broke last summer and that part of the zip you pull up has been lost, anybody know if i can buy just that part of a zip anywhere?
Last time i wore the sandals i had to close the broken one using duct tape not a good look

You'll need to replace the whole zip, I think...

Take them to a cobblers.

Buy a pair with zips cheap in a charity shop, or from clothing and swap over the zip pull. A good cobbler should have lots of spare bits for shoes as well.

Ahh never thought of a cobbler I'm going into town tomorrow so will pop them into the shoe repair place.

You can buy zip pulls at haberdashers or ebay sell them
