FXC 2.0 Compression Socks

$54.90 $49.90
/

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

 

SIZE CHART:

XS/S fits Calf 11.5"-13.5" | Shoe Size W 6-8

S/M fits Calf 12.5"-15" | Shoe Size M 7-9 / W 8-10

M/L fits Calf 13.5"-16.5" | Shoe Size M 9-11 / W 10-12

L/XL fits Calf 15"-18" | Shoe Size M 11-13

MODERATE COMPRESSION:

(20-30mmHg) - Recommended for sports and daily wear like prolonged sitting, standing, flying and travel. Makes working on your feet so much more comfortable.

COMFORT:

Our stylish performance compression socks hug and support your calf muscles with graduated compression, boosting performance during workouts and promoting rapid recovery afterwards.

SEAMLESS TOE CLOSURE:

We reduced the seam on the toe box for exceptional comfort and a great fit.

HIGH PERFORMANCE MATERIAL:

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

 

THE PURPOSE:

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.

BEFORE WASHING:

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.

LAUNDRY PRODUCTS:

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.

WASHING & DRYING:

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.

MOST IMPORTANTLY:

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.

DO NOT IRON & DO NOT DRYCLEAN
