Nike vapors feature comfort and light weight-durability is the down side. If you rotate them they will last longer-no 6 month warranty,Vapor 9's have low arch support.
Adidas B7 are heavier, last longer and have 6 mos warranty.I have B7 and they fit well, medium arch support.
I also have a pair of Adidas Galaxy Elites(black and orange stripe colorway-orange inside) they are very foot comfortable and light weight,they are not in high demand though,medium arch support,cost me $50. no toe drag support, these are very good in wear also,,B8's should have the full foot support of these and adidas would be in orbit. Peeps notice these shoes and ask me about them, All reviews of these are positive.
