Just got mine. I am a Womens' 8 with a wide foot (so sometimes the size chart for 8 is waaaaay too tight.... *cough* darn tough *cough*...). These fitsocks fit GREAT. There is quite a bit of stretchability as mentioned in the video due to the weave and fabric, but it fits perfect to my foot. I bought the hiker socks as well to try out. I'd definitely try some of their other fabric socks if they show up on massdrop.
