Looking for an expert or anyone who might know approximate value on these?

Looking for information on these vintage star chevron low top basketball shows. I've tried to look up some information, I am guessing they are from around 1981. They are in great condition, a couple smudges, no rips, tears, tread is immaculate. These are monsters, size 17. They've literally been shelved for the past 25 years. I have more pictures too.
