SLS3 FXC 2.0 Compression Socks - SALE

Regular price $54.90 Sale price $22.90

The new and improved high-tech FXC 2.0 compression socks for athletes have been designed, developed and tested by medical and health care professionals to ensure they meet your every compression sock need.

The FXC 2.0 compression socks feature a special Micro-Nylon which is softer than most compression socks making them easier to put on while still delivering true graduated compression, allowing for all the benefits of a well designed and fitted compression sock. 

The SLS3 FXC 2.0 compression socks deliver a controlled amount of pressure which is greatest at the ankle and gradually decreases around the calf.

Benefits of true gradient compression include:

  • better performance
  • increased energy for endurance
  • reduced muscle fatigue
  • shorter recovery time after a long or hard workout

76 % Micro-Nylon, 24% Spandex - odor eliminating super soft material that repels moisture, allowing your feet to stay cool and dry.



All of our SLS3 garments are created with great care, attention to details and passion. In order to maximize the life span and performance of your garment, we encourage you to consider our recommended care instructions.


Make sure all pockets are empty and the zipper is fully closed prior washing. Turn garment inside out. Avoid washing your garment alongside items with velcro, snaps, or rough fabric that can be abrasive.


Use mild detergent or soap designated for fine or delicate washables. Do NOT use fabric BLEACH or fabric SOFTENERS! Always avoid using fabric softeners with performance fabrics as the softeners may inhibit your garment’s wicking abilities.


Keep your colors bright and sharp by washing your garment alone or with similarly colored items in cold water and hang to air dry. Air-drying protects the lifespan of your garment’s elastic fibers and helps maintain the overall shape and performance properties.


This garment is NOT intended for extended use in chlorinated pools - chlorine is bleach and will destroy the Lycra/Spandex fibers in your garment! Remember to thoroughly rinse your garment after every use.
