As of right now, I am wearing a pair of Nike Legend IIs, and while I like them, I am still getting blisters on the bottom of my toes even after they are well worn in. I have/had a pair of Mercurial Vapor III's that I absolutely loved that I got three or four years ago, and I would still wear them except the stud is next to nothing and the support is dismal after so much wear and tear. Prior to my Legends, I was wearing the T90 Laser I, didn't like them enough, and switched back to my vapors, and then got my Legends. So now the question is, should I get a pair of the Vapor Vs, or try and find a pair of IIIs on ebay? How is the sizing of the Vapor Vs compared to the IIIs? Narrower, wider? Should I get the same size? Thank you for any comments you have, thanks again.
