I've tried other Jefferies socks for my son and after several washings to soften them up, he decided he liked them. OF COURSE, I can't find these specific socks anymore.
So I bought these athletic cut socks and the jury is still out on these. My son hates the strings inside from the seams-YES-they do still have seams, though they are smaller and softer. I had to go through all the socks and cut the long seam strings. This should have already been done to the socks since they are marketed to sensory issues customers.
They are very soft which my son loves. However, they are so soft that they tend to slip down his heel. I got the right size, but the ankle does tend to dip a little lower in the back than other athletic cut socks. A bigger size would not work because then he would have the heel space too high.
My son is wearing these socks so that's better than most socks, but they still have issues that need fixed to earn a better rating.
