MEDICOVI T40
End chronic foot, knee, and back pain with the power of water. Relief, or your money back.
Hard Floor: Long periods of standing and walking on any hard surface expose your feet to constant strain. Concentrated Pressure: With every step, your entire body weight is concentrated on your heel and arch, leading to rapid fatigue, foot pain, and later, joint pain too. MEDICOVI Water Insole: The water instantly absorbs every hard impact, smoothly distributes weight across the entire foot surface, and helps to immediately relieve pressure and pain.
30-day money-back guarantee
For this type, choose insoles one size smaller than your usual footwear. The water-filled technology will then perfectly adapt to your feet.
30-day money-back guarantee, even if the insoles have been worn and trimmed.

T40
What pain most hinders your every step?
Cheap gel or foam after a few weeks flatten into a thin pancake. MEDICOVI T40 instead uses water, which cannot be compressed – it absorbs hard impacts from concrete and immediately relieves overloaded points of the foot.

Heel pain
How does it work? The water enclosed in the capsule flows through internal channels with every step. This means your body weight doesn't press on the painful spot, but instead distributes evenly across the entire foot surface.
The Result? In the morning, you'll get out of bed without limping, and in the evening, your heel won't have that unpleasant burning sensation anymore.
If after a month you're not getting out of bed with ease in the morning, send them back to us, and we'll refund you the full amount.

Foot pain
How it helps: When walking on hard concrete, the water constantly equalises the pressure under your foot, and its continuous movement naturally improves circulation in tired muscles.
The effect: That troublesome feeling of heavy, hot legs that you have to lift and relieve as soon as you get home will disappear.
Try them during a normal day. If your feet burn just as much in the evening as they did before, send them back and we'll refund your money.

Fallen arches
How it helps: The water in the channels doesn't create constant support, but rather continuously and gently presses against the sole of your foot. This uninterrupted stimulation forces weakened foot muscles to work actively and engage with every step.
The effect: Your foot muscles don't get lazy; instead, they activate through natural movement. This allows your foot to cope better with the burden of its own weight, and your legs don't get tired as quickly.
Wear them in your shoes for a month. If you don't feel that your foot muscles are more active and your gait is more stable, return the insoles to us and we'll refund your money.

Knee pain
How it works: A special water capsule placed under the heel immediately absorbs the impact force from hard surfaces, right from the moment your foot first touches the ground. This effectively and mechanically protects your knee joints from continuous overload.
The result: No more of that annoying stabbing pain in your knees after a full day on your feet! In the evening, your knees won't feel stiff and tired anymore.
If after 30 days of walking you don't feel that your knees are less overloaded, return the insoles to us and we will refund your money.

Back Pain
How it helps: The water membrane cushions the pressure generated when walking on asphalt. This protects your spine, especially the discs, from the continuous, hard impact of your feet on the ground.
The result: You won't come home with a stiff spine that makes it hard to even bend down in the evening.
If after a month you don't feel that your spine is more relaxed, send the insoles back and we will refund your purchase price.

Balance Issues
How it helps: Water flowing through the internal channels constantly stimulates the sole of your foot. This sensory stimulation activates the small muscles in your foot, which are directly responsible for maintaining stability and correct posture.
The result: Your foot better senses the surface beneath it, your step is more secure, and you gain significantly more confidence when walking both indoors and outdoors.
Try them for 30 days during your daily movement. 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.
If you have any questions, please feel free to contact us. We will reply as soon as possible, within 24 hours on working days.

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 along its entire length – from the heel to the forefoot. It provides optimal hydraulic resistance without causing unnecessary lifting of the foot in the shoe.
100% flat profile: The insole does not have any artificial, plastic arch support or a raised heel cup. The foot rests in a natural position, which prevents improper ankle tilt.
Compatibility: What footwear are they suitable for?
Thanks to its ultra-flat profile and precise 5 mm thickness, the T40 model is incredibly versatile, ideal for open-toed footwear, everyday shoes, and light work shoes.
PERFECT FOR:
- Sandals and open summer footwear: This is the ideal solution! Thanks to its flat shape, the insole doesn't protrude from the open sides of the footwear, and a special bottom layer securely holds it to the sandal's footbed, preventing it from slipping out while walking.
- Light work footwear (Medical, catering, and services): Created for people who spend entire shifts on their feet, standing on hard surfaces such as tiles or linoleum. Ideal for medical clogs, work sandals, and light, white footwear (for nurses, doctors, chefs, waiters, or customer service staff).
- Sports and everyday footwear: Standard urban trainers, sneakers, outdoor shoes, and closed walking shoes.
NOT RECOMMENDED FOR:
- Heavy construction footwear and sturdy safety shoes: The T40 model is not designed for massive steel-toed work boots used on construction sites or in production/metalworking halls.
- Narrow stilettos and elegant high-heeled court shoes: The extremely tapered toe and steep angle of the shoe physically prevent proper water displacement and the full functioning of the hydraulic system.
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
If possible, remove the original insole from your shoe. For sandals and summer footwear where the insole cannot be removed, simply place the Medicovi insoles directly on top of it.
For closed shoes, place the original insole against the Medicovi T40 (align them at the heels) and trim the front, water-free part of the Medicovi insole to match the shape of the original.
Insert the insole into the shoe with the black, fabric side facing upwards (the white side with the visible hydrodynamic relief should face downwards, towards the sole).
