At the left is a small socks 5-pack!
The pack of socks contains 5 different styles for boys anklet socks. They are all small though so these would only fit little kids. The first pair has running Sonic with rings, the second is gray with a gray Sonic and a phrase, but you can't tell what it says, the 3rd has thumbs-up Sonic in checkers, the 4th is a white pair with just the 'speed boost lines' shapes all over and the final pair has thumbs up Sonic with more rings. The designs are all a part of the fabric, so they can't peel off/go bad/etc. This is a Segashop item in 2018 and they're 14.95 for the whole set.

At the right is another 5 pack of boy's-sizes ankle socks! 
Why it keeps doing 5 packs is a mystery, same with the answer to why they only do these in super little kiddie sizes only. (It's too bad) because the sock designs are pretty fun. You get 1 pair dedicated to Sonic, Tails & Knuckles with their name on each. The other 2 pairs are either white or black, with a group of rings only. Notice that the designs are woven into the socks themselves, so they can't ever wear off/go bad. This is 20 dollars in the Sega Shop setting them a little under 5 dollars per pair. This is a 2018 item.
