Yes...here comes another variation on Sonic socks.
This is yet another pair of 'forward facing Sonic classic face' all blue socks. This time they're knee-highs, which have been seen on before on a previous page, but now they combine the knee-high length with the wacky fetl spike add-ons that are sewn to the backs to make the socks "3D" and add an extra character element. As before, the design is actually part of the sock, made with the woven threads so it has no fear of wearing off, but it can be stretched/distorted as it's worn.
These are a Spencers' Gifts item that should be about 9.99 for a pair in the summer 2017 season. These are a fun, adult size (so, should fit any feet) pair of wacky socks if you didn't already have something super similar.
