SIMMS Mid-Calf Sock Liner is a lightweight, moisture-wicking layer built for summer wet-wading and for layering under standard socks to add warmth on chilly days.

The body, heel, and toe boxes use polypro yarn to wick moisture and stay highly breathable, while nylon yarns in high-wear zones boost durability for long days on the water.

Mid-calf height offers versatile coverage under boots and works well under a heavier sock for protection against abrasion.

This liner also shines under flats boots, shielding feet from small sand particles and debris that can enter boots during salt flat wading.
