Reading the listing

What to check before you buy this pair

Message on the soles

The bottom of the foot spells out HAPPY BIRTHDAY GRANDSON in bold letters, visible when feet are up on a coffee table. The top displays balloons and party hats against dark blue.

Knit fiber blend

A blend of 80 percent cotton, 15 percent nylon, and 5 percent spandex gives the fabric a soft feel against bare skin while maintaining stretch around the calf and heel.

Men sizing specs

Sized for everyday wear, this pair fits US men shoe sizes 7 to 13 and corresponds to sock sizes 8 to 14. The cuff stays in place without bunching in shoes.

Packaged in a box

Each order includes one pair packed inside a printed gift box ready for a milestone birthday party, family gathering, or small celebration.

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.
