Reading the listing

What to check before you buy this pair

Milestone gamer print

Balloons, birthday cakes, party hats, and wrapped presents dot the upper section. The soles carry the phrase LEVEL 21 UNLOCKED in textured, non-slip ink that adds traction on hardwood floors and tile.

Cotton rich knit

The fabric combines 80 percent cotton with 15 percent nylon and 5 percent spandex. Cotton provides everyday breathability, while the nylon and spandex blend helps the cuff stay up around the calf.

Sizing specifications

This cut fits men and teens wearing US shoe sizes 6 through 13. It also accommodates women size 7 and up. The stretchy ribbing pulls on smoothly over bare feet.

Ready gift box

One pair comes tucked inside a themed gift box. The packaging keeps the socks flat and neat for passing across the table at a twenty-first celebration.

Specification as the manufacturer wrote it, wording and all:

  • BIRTHDAY GIFTS: These socks feature birthday gifts, hats, cakes, balloons, and other elements on the top, while the bottom features a hilarious secret message written in non-slip ink: "LEVEL 21 UNLOCKED".
  • SIZE: Caters extensively, fitting most men's and teens' US size 6-13 and women's size 7 and above. Each exclusive gift box contains one pair of 21st birthday socks.
  • QUALITY MATERIAL: Experience the soft touch of funny socks made from 80% cotton, enhanced with 15% nylon for durability and 5% spandex for the perfect stretch.
  • 21ST BIRTHDAY GIFT IDEAS: Delight someone special on their birthday with the perfect gift.

Sizing

Match the shoe size, not the sock size

Novelty socks from this label are sold by the shoe size they fit, and the range on the listing is wide. If the wearer sits at the top of the range, the cuff will be shorter on them than in the photo.

How the sizes work

1Find the shoe rangeEvery product page repeats the range from the label, usually men US 6 to 13 or women US 5 to 10. If the recipient is outside it, the sock will still go on and it will sit lower than the photo.
2Check the heightCrew hits mid calf. Knee-high and thigh-high pairs list a leg length in inches, and that number matters more than the shoe size for anyone tall.
3Look at the stretch contentSpandex and elastane sit between three and fifteen percent in this range. The higher end takes a wider calf. The cotton-heavy pairs stretch less and hold shape longer.
