Product Information
How It Helps
Firm graduated compression runs from the foot through the calf to provide structured lower-leg support. Targeted compression zones around the arch and ankle add support where it is needed most, while the over-the-calf design provides consistent coverage during movement and extended wear.
Why You’ll Love It
- Firm 20-30 mmHg graduated compression
- Provides support from the arch through to the calf
- Targeted compression zones support the ankle and arch
- Moisture-wicking construction helps keep feet comfortable
- Breathable design is suitable for extended wear
- Thin, flexible profile fits comfortably inside most footwear
- Stay-put construction helps reduce slipping and bunching
- This listing is specifically for the X-Large size
Is This Right for You?
The FS4+ is designed for people wanting firm graduated compression across the foot and lower leg during activity, recovery, travel or long periods on their feet. This X-Large size suits an ankle circumference of 30-35 cm and calf circumference of 37-51 cm.
More Ways to Use It
For the best fit, measure both your ankle and calf circumference before ordering. X-Large also corresponds approximately to men’s US shoe sizes 13.5-15, UK sizes 14-16 and EU sizes 47-50, but circumference measurements should be prioritised when selecting compression socks.
Our Verdict
The FS4+ combines the practicality of an over-the-calf sock with targeted compression throughout the foot and lower leg. We particularly like the full-length support, breathable construction and firm graduated compression for people who want one product covering both the foot and calf.
