I purchsed thesse socks for my child with SPD, she is very sensitive about her socks and the Jeffferies athletic seamless socks were a lifesaver and something she wears alost exclusively.  Thought these would be a slightly more dressy option for us and ordered quite a few of them.

When they arrived, although they have no seam persay across the toe, there are "bumps" in the corners and even the dreaded "strings" at the ends of where the seams would be. I had to get sissors and painstakingly cut each string off, and we still need to inside out them b/c there is that residual "bump" even with the strings removed. ("Sensory" parents know what I mean lol!) It is a lot of workring to get these into a "tolerable" range for her to wear, and my point in buying seamless socks is to avoid yet another clothing hassle.

Jefferies athletic seamless are wonderful, but these were not nearly as good. Nice quality sock, but don't call it seamless!
