I got them yesterday and love them. When it comes to size  I am glad that I listened to other feedback, I always wear a size 8, my other Asics are size 8. At the advice of other feedback, I ordered 8.5 and they fit perfect. The 8 would have been to small. If you have a wide foot these may not be the one for you. I am not skinny footed but not quite wide , if my foot were any wider they would be to tight for sure and that is not usually an issue with Asics. These have the tongue attached almost like those slide in shoes but with laces added. I walked on treadmill yesterday and today and they fit perfect no break in needed. They are so bright and vivid, my husband calls them a box of crayons ,can't wait to wear to Disney World next month :)
