These socks are designed to be very stretchy and very thin, to be used inside a liner if necessary to give a measure of perspiration control, the leg circumference range of each is 21cm to 40cm circumference. They are made from very fine Coolmax ® spun with nylon impregnated metallic
silver. Stretched thickness is 0.5mm. The two legs in the photo illustrate the width stretch range.
Note: Each of these socks have the same proximal stretch range of 21 – 40cm circumference, although, naturally, as the circumference of the leg increases the length of the sock decreases.
