ISO! *not for sale*

I am desperately looking for either of these 3 Nike sneakers in a size 7! The first one two are the Nike TR Fit 3, I am looking for it in either black or grey, like the photos show. Or the 3rd shoe which is called the Nike TR Fit 5, in the black/Grey color! But if you have these or know someone who has these or similar to these, please notify me! I am willing to buy for $50 or less, or I am willing to negotiate a price with you so we can come to an agreement. Thanks guys!
