Unfortunately the rubberised coatings on some binoculars (and, indeed, the focusing and zoom rings on some camera lenses) go like that in non-optimum storage conditions - i.e warm moist areas, such as a kitchen cupboard. I'm afraid I know of no way of curing this - you may need to take them to a repair facility and ask their advice.
Your question is listed under "Zhumell Oberwerk 45 25x100 Astronomy binoculars". If these are what you have then they're an extremely high end expensive specialist item and will need professional realignment. I'm assuming that if you do own a pair of these then you're knowledgeable enough to have done all you can to adjust them correctly.
I suspect that you have a regular pair of 10x50 or similar binoculars, with a centre focus wheel and hinges. If this is the case then try to wiggle one of the eyepieces back and forth: if you can easily move it and the other eyepiece remains steady then you have a broken hinge. This is a very common fault especially if your binos have been dropped or if they've been stored in their case upside down (i.e.standing on the eyepieces).
A broken hinge is normally a write-off as there is rarely sufficient area to us epoxy glue on and the metal used is not usually suited to being brazed. Even when the hinge can be repaired it's normally permanently misaligned.
Either resign yourself to using one half of your binoculars or buy a new pair. In the UK LIDL regularly sell a pair of Meade 10x50 binos of excellent quality for just over £10 and that's only a little more than a bottle of epoxy resin glue costs. You may be interested to know that one of the world's most successful supernova spotters does so in his back garden in the UK using just half a pair of old 7x50 binos.
I am an avid birder and sent my Zeiss and B & L binoculars to Larry at reichinstruments.com - his prices were great and service was quick. He restored them to A1 order and I'll use him again. I recommend him highly! Nice guy to deal with.
