TX4 - Approach Shoes

I've got a pair of la sportiva tx4 and the inner laces have come part. How do I go about fixing them as I've taken them to a few shoe shops in westen Australia and they can't fix them.

Good Morning

I am sorry to hear you are having an issue with your TX4 shoes. How Old is the shoes and can you provide us with a few pictures if possible? 
If you send the pictures to web@mountainequipment.com.au.

Had a look at a pair of the TX4's and on the back by the heel is where the inner laces connect. It is one piece of lace that is fed through the whole shoe and then the ends joined at the back. So not sure who to recommend for a repair of that kind.

Thanks Hannes
