Hello candidate, first of all slippers are allowed allowed in exam hall. So you can wear it. But as it has bit of metal it will not  create  that much problem .but i will suggest you to wear slipper without metal. So be tension free. 

Thanks.

Hello Student,

No, you are not allowed to wear any thing that contains metal whether it be a slipper or a shirt with metal buttons. You can only wear simple slippers or sandel. Any kind of metal substance are strictly prohibited.

Hope it helps you

Thank you
