Description
OS1st FS6 Performance Foot Sleeve – Plantar Fasciitis & Heel Pain Support
The OS1st FS6 Performance Foot Sleeve provides targeted compression and support around the arch, heel, Achilles tendon and ankle. It is designed for people experiencing plantar heel pain, plantar fasciitis, arch discomfort or foot swelling, and can be worn during everyday activities, inside shoes, during exercise or while resting.
The FS6 uses six zones of targeted compression through OS1st's Compression Zone Technology®. The graduated compression design provides supportive pressure around the foot while the lightweight, moisture-wicking nylon construction is designed to remain comfortable during extended wear. Silver Ion treatment helps manage odour during active use.
Worn under socks and inside shoes — so you get compression support throughout your entire day without changing your shoe fit.

FS6 vs Gel Sleeves vs Orthotics — Which Do You Need?
The FS6 provides compression-based support — it wraps around the foot to provide external pressure and support, which works differently from cushioning or structural correction. Walker's Gel Plantar Fasciitis Sleeves cushion the arch and heel with a mineral oil gel pad — they reduce impact but don't provide compression. For structural biomechanical correction, Trekker orthotics or Formthotics insoles sit inside the shoe and influence foot loading from underneath. Many people use the FS6 alongside orthotics — the compression sleeve provides external support while the orthotic provides structural correction inside the shoe.
Sizing
| Size | Arch Circumference | Approx. Shoe Size (EU) |
|---|---|---|
| XS | 10–15 cm | EU 32–34 |
| S | 13–20 cm | EU 34–37 |
| M | 18–25 cm | EU 37.5–43 |
| L | 23–33 cm | EU 43–47 |
| XL | 28–38 cm | EU 48–51 |
| XXL | 33–46 cm | EU 51.5+ |
Measure your arch circumference carefully before ordering. The sleeve needs to provide compression without being excessively tight. If you are between sizes, the larger size is generally more comfortable for extended wear.
Care Instructions
- Hand wash with mild soap, hang to air dry
- Do not use bleach or fabric softener
Frequently Asked Questions
What is the OS1st FS6 Foot Sleeve?
The OS1st FS6 is a compression foot sleeve designed to provide targeted support around the arch, heel, Achilles tendon and ankle. It is commonly used by people looking for additional support for plantar fasciitis, plantar heel pain, arch discomfort and foot swelling.
Does the FS6 help with plantar fasciitis?
The FS6 is designed to provide compression and support around the arch and heel, which may help manage discomfort associated with plantar fasciitis. Plantar fasciitis can have multiple contributing factors, so a compression sleeve is one potential component of management rather than a guaranteed treatment. Persistent heel pain should be assessed by a podiatrist.
What is the FS6 used for?
The FS6 is designed for people seeking foot support for plantar fasciitis, plantar heel pain, arch discomfort, heel discomfort and swelling. It can be worn during everyday activities, inside shoes, during exercise or while resting.
Can I wear the FS6 all day?
Yes — the FS6 is designed for continuous all-day wear. Many users put them on first thing in the morning and keep them on until bed. The lightweight nylon is comfortable enough for 12+ hour days.
Do I wear these under or over socks?
Under socks. The FS6 sits directly against the skin of the foot, and you wear your normal socks and shoes over the top. The low-profile design means they don't change your shoe fit.
Can I wear the FS6 overnight?
Yes — the FS6 can be used while resting and is designed by the manufacturer for overnight use. Wearing them overnight maintains gentle support on the plantar fascia while you sleep, which may help reduce the discomfort many people experience with their first steps in the morning. Ensure the sleeve is comfortable and not excessively tight. If you experience numbness, tingling or increased discomfort, remove it and seek professional advice.
Can I wear the FS6 while running?
Yes — the FS6 can be worn during exercise and sport. If you are experiencing persistent pain while running, it is advisable to have the underlying cause assessed by a podiatrist rather than relying solely on a compression sleeve.
Is the FS6 suitable for swollen feet?
The FS6 provides graduated compression and is designed for use with swollen feet. However, unexplained or significant swelling should be assessed by a healthcare professional, particularly if it is sudden, one-sided, painful or associated with other symptoms.
Can I use the FS6 with orthotics?
Yes — the FS6 provides compression while orthotics provide structural support inside the shoe. They serve different purposes and work well together. Many podiatrists recommend this combination for plantar fasciitis management.
How long do they last?
With daily wear and regular hand washing, most people get 3–6 months from a pair before the compression loosens. Replace when you notice the sleeve feels less snug or supportive than when new.
What is the difference between the FS6 and an orthotic?
The FS6 is a compression sleeve that wraps around the foot to provide external support. An orthotic sits inside the shoe and is designed to influence foot loading and provide support from underneath the foot. They serve different purposes and may sometimes be used together depending on the individual. For orthotics, see our Trekker range or Formthotics insoles.
