What is it?

The TheraStep Plantar Fasciitis Arch Sleeve is a flexible, easy-to-wear support designed to cushion the arch and heel area. It combines a stretchable sleeve with a built-in massaging gel pad positioned beneath the arch to provide soft, consistent support throughout the day.

Unlike rigid orthotics, this sleeve focuses on cushioning and pressure distribution rather than structural correction. The gel insert is infused with medical grade mineral oil, which is designed to help soothe and moisturise the skin while delivering gentle, targeted support.

Supplied as a pair, the sleeves are suitable for wearing with or without shoes, making them adaptable for use at home, at work or during light daily activities.

Who is it for?

This arch sleeve is suitable for adults experiencing mild to moderate heel or arch discomfort, particularly symptoms commonly associated with plantar fasciitis.

It may be beneficial for:

• People who spend long hours standing or walking
• Those with heel pain on first steps in the morning
• Individuals with tired, aching arches
• Users seeking soft cushioning rather than firm orthotic control
• Anyone looking for a discreet, low-profile comfort solution

The universal “one size fits all” design accommodates a wide range of adult foot sizes due to its stretch construction.

What does it help with?

The sleeve is designed to help reduce discomfort by cushioning sensitive areas and redistributing pressure across the arch and heel.

• Plantar fasciitis: May help reduce strain through gentle arch support and cushioning.
• Heel pain: Soft gel pad absorbs some of the impact during walking.
• Arch fatigue: Provides light support to ease tired, aching feet.
• Pressure discomfort: Distributes load more evenly across the midfoot.
• Dry or rough skin: Mineral oil infusion helps maintain skin softness during wear.

It is important to note that this product is designed for comfort and support. It does not replace medical treatment or structured orthotic therapy where clinically required.

How does it work?

The sleeve works through a combination of compression, cushioning and targeted gel placement.

The stretch fabric provides mild compression around the midfoot. This can create a sense of stability and support without restricting natural movement.

The integrated gel pad sits beneath the arch. As you walk, the gel gently compresses and rebounds, helping to absorb some of the forces that would otherwise concentrate on the plantar fascia and heel.

The medical grade mineral oil within the gel is gradually released during wear. This helps maintain skin hydration, particularly useful for individuals prone to dry or rough skin on the feet.

Expected Comfort & Use Timeline

First use

You should notice immediate cushioning under the arch. The sleeve should feel snug but not tight or restrictive. Walking comfort may improve straight away due to the added padding.

Short-term (first few days)

As you wear the sleeves consistently, you may experience reduced sensitivity in the heel and arch during daily activities. Allow your feet time to adapt if you are not used to wearing supportive products.

Ongoing use (weeks)

With regular wear, the sleeve can provide continued cushioning support during standing and walking. It is intended for symptom management and everyday comfort rather than structural correction.

Fit & Comfort Check

Common Mistakes to Avoid

• Expecting rigid arch correction – this is a cushioning support, not a custom orthotic.
• Wearing inside very tight shoes that compress the foot excessively.
• Over-wearing immediately without allowing your feet time to adjust.
• Positioning the gel pad incorrectly away from the arch area.

How to Use

1. Ensure feet are clean and dry before application.
2. Slide the sleeve over the foot so the gel pad sits comfortably beneath the arch.
3. Adjust for a smooth, wrinkle-free fit.
4. Wear with socks and shoes or barefoot as preferred.
5. After use, hand wash in mild soap and allow to air dry fully before re-wearing.

Discontinue use if irritation occurs and seek professional advice if symptoms persist.
