natural softness with everyday performance.
Surino™ combines the smooth comfort of suri alpaca with the familiar softness and stretch of merino — then builds it into a lightweight sock made for movement, daily wear, and long hours on your feet.
01
suri alpaca comfort
Soft suri alpaca brings natural moisture movement, breathable comfort, and a smooth feel to a lightweight performance sock.

Merino softness
Merino wool adds familiar next-to-skin softness and stretch, helping the sock move comfortably through active and everyday wear.
Mechanism · Merino wool blend
03
Movement-mapped fit
Targeted zones support comfort where your foot moves most, while breathable areas help keep the fit light and low-bulk.
Mechanism · Zone-mapped construction
04
