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

Looking for information on these vintage estrella chevron low parte superior, arriba baloncesto 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 más pictures too.
