If you took it to the menders and they gave them back still broken, you should find another mender and get your money back from the first one! But seriously, if you love those boots, and you think they are worth mending, get a professional to do it. I've bodged repairs with things like this before, and usually end up with worse problems, or even having to throw away much loved shoes or boots. Don't risk it!!
