MEDICOVI A40
End heavy, aching feet after a long day with the power of water. Relief, or your money back.
Work Footwear: Hours spent on your feet in rigid or protective footwear mean constant pressure on your feet, which classic insoles cannot alleviate. Static Load: Your entire body weight presses on your heel and arch for many hours, which can cause burning foot pain, rapid fatigue, and consequently, overload of your joints or back. Water-filled ESD A40 Insole: Water immediately absorbs hard impacts, smoothly distributes body weight across the entire surface, and effectively helps relieve tired legs and lower back.
30-day money-back guarantee
30-day money-back guarantee, even if the insoles have been worn and trimmed.

A40
What pain most hinders your every step?
Ordinary foam in work footwear quickly flattens under your weight and stops cushioning. Instead, the professional MEDICOVI A40 model uses incompressible water – it absorbs hard impacts from industrial floors and immediately relieves overloaded points of the foot.

Heel pain
How it works: With every step, the water enclosed in the capsule flows through internal channels. This ensures that your body weight doesn't press directly on the painful area, but instead distributes evenly across the entire surface of your foot.
Effect: Noticeable relief from your very first steps in the morning, and a palpable reduction in fatigue and burning heels after a full day spent in work footwear.
Test them at work for a full 30 days. If you don't wake up feeling lighter in the morning, send them back to us and we'll refund the full amount.

Foot pain
How it helps: When walking on hard concrete, the water constantly equalises pressure under your foot, and its continuous movement stimulates tired muscles, supporting better circulation.
Effect: Significant relief from the feeling of heavy, hot legs. In the evening, after returning from work, you'll no longer feel such a strong need to immediately elevate your legs.
Try them during your workday. If your feet burn just as much as before in the evening, send them back to us, and we'll refund the full amount.

Fallen arches
How it works? The water in the channels doesn't create rigid support, but instead constantly and gently presses against the sole of your foot. This continuous stimulation activates weakened muscles, forcing them to work and engage with every step – especially in work footwear.
The effect: Your foot muscles don't slack off; quite the opposite – they are naturally activated by movement. As a result, your foot copes better with all-day strain, and your legs tire less quickly.
Wear them in your shoes for a month. If you don't feel your gait is more stable and your foot muscles are less tired, return the insoles to us, and we'll send you your money back.

Knee pain
How it helps: The water capsule under the heel absorbs pressure from hard surfaces with every step. This mechanically protects your knee joints from continuous overload when walking and standing on concrete.
Effect: Significant relief from pressure and stiffness in your knees after a full day on your feet. Your joints no longer have to endure the hard impacts that were previously transferred to them from inflexible footwear.
If, after 30 days at work, you don't feel that your knees are less overloaded when walking, return the insoles to us and we will give you your money back.

Back Pain
How it helps: The water membrane cushions the pressure created when walking and standing on hard concrete or asphalt. The spine, and especially the discs, are thus protected from the continuous, hard impact of your feet in rigid footwear.
Result: Significant reduction in lower back fatigue after a shift at work. You will no longer return home with such a stiff spine that would limit you in your daily household activities.
Wear them for a month at work. If you don't feel your spine is more relaxed at the end of the day, send the insoles back, and we will refund the full amount.

Balance Issues
How does it work? Water, flowing freely through the insoles' internal channels, constantly stimulates your foot. This sensory stimulation activates the small muscles in your foot, which are crucial for maintaining stability and correct posture, especially whilst working.
The Result: Your foot senses the ground much better, every step, even in heavy footwear, becomes more confident, and you gain unrivalled stability and safety when moving around your workplace.
Try them for 30 days during your daily movement at work. If you don't feel that you're walking more stably and with greater confidence, send them back to us, and we'll refund the full amount.
Water Wave Therapy: Walking that actively suppresses pain
Controlled Hydraulic Wave: With every step, the fluid reacts instantly. Flowing through special channels, it evenly distributes body weight across the entire surface of the foot and effectively cushions hard impacts.
What makes it work so effectively? Anatomical Mechanism
- Better Blood Circulation: The gentle movement of water constantly stimulates the sole of the foot. This micro-stimulation naturally oxygenates tissues and relieves tension.
- Instant Stabilisation: Water reacts in fractions of a second. Pressure immediately distributes over a larger area, which supports the stability of the entire body – from heels to spine.
- Continuous Micro-Movement: The constant movement of the water surface turns an ordinary walk into regeneration. With every step, the most overloaded points of the foot are relieved.

How to cope with long days on your feet in the bakery without pain and fatigue

Real-life story: Baker Gabriela (35 years old)
“All day on my feet in the bakery, and then the merry-go-round of duties with the children. My legs and back could barely cope anymore.”
BEFORE: Leg and back pain, and constant pressure after hours spent on my feet.
NOW: All day on the go with truly enormous relief, without the previous pressure and muscle fatigue.
“I’m a baker, a mum, and I spend hours on my feet every day. With baking and cleaning, you don’t even realise how much your legs take a beating until the pain starts. Medicovi insoles have brought me truly enormous relief. I walk all day and don’t feel that pressure in my legs or that fatigue I used to. If you have a similar problem, they will help you just as much as they helped me.”
Insole specifications
Official EU MDR Certification
Classification: Registered Class I Medical Device in full compliance with the European regulation MDR 2017/745 (Medical Device Regulation).
What does this mean in practice? The product has undergone a rigorous clinical evaluation regarding its biomechanical properties and material safety. This is not just an ordinary accessory, but a certified medical device designed to effectively relieve pressure and musculoskeletal pain.
Dimensions, thickness and profile
Constant 5 mm thickness: The water capsule maintains a precise 5 mm thickness. It provides constant hydraulic resistance, effectively absorbing shocks, without unnecessarily lifting the foot in work footwear.
Deep Heel Cup: The raised profile in the heel area securely holds the heel in the centre of the water cushion. This prevents the foot from sliding sideways and protects against sprains, even in heavy protective footwear.
Anatomical side guidance: The raised edges in the middle part of the insole naturally support the arch of the foot and keep it in the correct alignment. This prevents improper ankle tilt and excessive fatigue during all-day standing on hard surfaces, such as concrete.
Compatibility: What footwear are they suitable for?
IDEAL FOR:
- Heavy industrial and safety footwear: This is their natural habitat! They are a perfect fit for chunky work boots with steel or composite toe caps, accompanying you in factories, warehouses, workshops, or on construction sites – wherever you need maximum support.
- Robust sports and outdoor footwear: They will perform excellently in durable trekking boots, stable walking trainers, and wider-cut recreational footwear – wherever your foot craves security and stability.
- Wide and spacious footwear: Any shoes that offer enough room for the comfortable placement of the insole and its stabilising side support.
UNSUITABLE FOR:
- Sandals and open summer footwear: Absolutely not! Their raised edges and deep heel cup would cause the insole to protrude from the shoe, losing its stabilising power.
- Narrow and elegant dress footwear: Narrow loafers or elegant high heels simply do not offer enough room for the robust profile of this insole.
Sizes and customisation by trimming
Available sizes: Standard European double sizes: 34-35, 36-37, 38-39, 40-41, 42-43, 44-45, 46-47.
Where you CAN trim: The front third of the insole (toe area) is completely water-free. On the white underside, there are precise cutting lines (e.g. 42-8, 43-8). Here you can shorten the insole with scissors, both in length and at the sides, to customise it to the shape of your shoe's toe.
Where you MUST NOT trim: Never trim the side edges or the heel! That's where the hermetically sealed hydraulic chamber is located. If it is damaged, water will leak out.
Instructions for correct use
Remove the original insole: Always completely remove the original insole from every shoe – whether it's a work shoe or a sports shoe. This will ensure the A40 insole has enough space.
Trim to the perfect shape: Place the original, removed insole onto the Medicovi insole (align them precisely at the heels). Then, trim the front, which is the non-water-filled part, with scissors, mirroring the shape of the original insole.
Correct placement in the shoe: Insert the insole into the shoe with the textile side facing upwards (the side with the visible hydrodynamic relief should be facing downwards, towards the sole of the shoe).
