This 6 (or really 8) pack of socks appears in Walmart only in fall season 2020. So go grab 'em because they're reasonable in price at about 9 dollars for the whole set!

These are modern designs, with the character face directly on the top of the foot alone. The designs are part of the sock's fabric/weave so they can't ever wear off of the sock or go bad. The faces of the characters (since they are portrait socks) are also large enough to appear smooth/well done instead of jagged or wrong like what happens when detail vs stitching gets too fine/tiny. You will get Sonic on black, Knuckles on gray, Shadow on burgundy, Eggman on black, Tails on blue and "No Time For Games" slogan in black on a mottled gray sock. What about that 8 pack? Well, it comes with "Bonus" 2 extra pairs of socks built in--but these are generic, simply a black pair and a dark gray pair with no design. They're bundled in to pad the sock-count and attempt to make more of a bargain. Which---at the price these are it actually kind of does because about a dollar a pair is really ok.
These will be found (probably) in a free standing cardboard display cubby that WILL have the Sonic logo on the side. Rummage the cubbies until you find the right size sock, as these DO come in SM, Med, L, XL so even if it's marked for kids getting the big size may make it still fit you. They are no-show/ankle socks so you probably can't wear it with hightops shoes. The designs are quite nice, as is the inclusion of Eggman in the set. Going with the large format faces really helps these look good. A recomended product.
