The ideas behind details of the socks are great - arch support, padding, lightweight, quick drying, silicone pad on the back to keep them in place on your heel. The problems I have found are: the toes are funky - there is too much room at the pinky toes. Since the socks are foot specific, the toe of the socks should slope down to fit the foot anatomically, but instead, they go straight across leaving too much empty space at the pinky toe. The second problem is the sizing. I wear a size 11, ordered M/L, and they are too big. There needs to be a S/M. Overall, they work well enough to not be worth sending them back, but there should be some small tweaks made to refine them further.
