This is a very lightweight shoe but be careful if you are in need of cushioning because these are minimalist-like shoes and after less than 20 total miles my knees are hurting like I have owned them 300 miles. They also run a little large: I wear a 13 in Adidas but this one came a half-size or so large. Another note to remember is they are are for running nice, smooth, and dry roads because of the outsole pattern. I'm not mad at Adidas about the shoe but I wish the other reviews were more accurate since I am overseas (Iraq) and can't try the shoe on for fit.
