The adidas ZX 710 dates back to 1987 & is one of the more underrated entries in the ZX line. That emphasis on heel support & the Dellinger web cushioning made this a technical runner that fetched crazy e Bay money over the years. This 2014 resurrection is a closely supervised (by fanatics) reissue that gets the 1:1 retro treatment for a perfect shape that puts the usual banana-shaped releases in the shade. An excellent shoe in its original colour way for those who appreciate great athletic design.
