The new Nike Cortez all seem to have this neon thing going on, obviously with the yellow but the other colours seem very vibrant as well. I have to say I'm a fan of the blue and red, I like the purple but how much wear will I get out of purple trainers? Never been a massive fan of neon, so think Ill pass the yellow ones. Its a shame I tried on the old nylon pack in Nike town the other day, I should of got them but the sales assistants put me off.
