At this price point I wasn?t expecting it. These are very good for my son But it did run on xmp settings at 3466mhz out the box. Comfortable as well as very stylish! I normally wear an 8 but I would size down with these. did not. I really hope these last a long time so I dont have to modify this review in the future. Super disappointed ?? They look great but I might want a different type of sole for my foot to go against the next time. Comfortable enough that they dont hurt my arch after long hours of standing, as I had this issue with other Nike trainers.
