What are terry loops in a sock?
Terry loops are small raised loops knitted inside a sock for cushioning and moisture absorption, placed where the foot needs padding.
How terry cushioning is made
Terry is knitted at the same time as the base fabric. Selected needles pull an extra yarn into loops that stand up on the inside of the sock, creating a soft pile that compresses under load and springs back.
Full, half, and zoned terry
- Full terry: loops throughout the foot and leg for maximum warmth and padding, common in ski socks and boot socks.
- Half terry: loops under the foot only, with a lighter leg.
- Zoned terry: loops placed where impact happens, such as the heel, ball of the foot, or toe, with thinner mesh zones for ventilation. This is the usual build for athletic and quarter socks.
Specifying it
Terry adds yarn, weight, and knitting time, so it moves the price. Put the cushioning map on the tech pack: which zones, what pile height, and which yarn. Loops in cotton or polyester blends feel different, and the right choice depends on whether the sock is for running, walking, or cold weather.
