I bought these for indoor workouts and they are PERFECT. I am not an outdoor runner but I imagine I would want more support for say a trail run. They are light mesh top with a sturdy but not thick or heavy sole. The colors are the absolute best I've seen. Subtle purple and grey with a bit of neon orange. Not so clown like as some...the sizing is true. I bought an 8.5 and they fit but no room to spare.
