In my initial review, I liked the look and lightweight features and commented on how quiet they are - you can literally "sneak" around the house. Still true. I've also found that despite reviews saying they're small, they fit perfectly. Truth at your fingertips. However, after a few more days of use, it became apparent that they were so tight on my legs that they left red marks. I gave them 10 more days to stretch. I loosened the laces enough that there was little left to tie a double knot. Nothing solved the problem of tightness or red spots. I keep them as a backup but bought the roomier and springier Ghost which is still the best running shoe out there at this price point.
