Test them for 30 days.

Try the T40 insoles for flat feet and fallen arches for a full 30 days. If you don't feel your arch working and your feet last longer without fatigue, we'll refund your money — even if the insoles have been used. No unnecessary questions or forms.

I WANT TO FEEL RELIEF

Water wave technology that helps exercise the foot arch

Controlled hydraulic wave: with every step, the fluid reacts instantly. Moving through the channels, it evenly distributes body weight across the entire surface of the foot and helps soften every step.

Why does it bring relief? The secret lies in hydraulics!

Circulation Support: The gentle movement of water constantly stimulates the sole of your foot — this can support blood circulation and help relieve tension.

Instant Stabilisation: Even pressure helps relieve the overloaded arch of the foot.

Continuous Micro-movement: The arch of the foot does not remain in one overloaded position all day long.

Mrs Aoife from Limerick has been struggling with flat feet (pes planus) since birth and has probably tried everything. “T40 is the first insole where I feel that the arch of my foot is genuinely working — it’s not just passively supported.” With flat feet, which have accompanied her throughout her life, she finally feels a difference: the foot engages independently, instead of transferring all the weight to just one point.

Why have ordinary insoles so far not helped you at all?

ORDINARY INSOLES (Gel or foam)

Ordinary gel and foam insoles only passively support the fallen arch. The foot quickly gets used to such support, and the arch muscles stop working. In the case of flat feet, this leads to exactly what you want to avoid: according to research, the muscles weaken by as much as 17% within 12 weeks (Protopapas et al., Clinical Biomechanics, 2020), and the arch collapses even further in the long term.

MEDICOVI WATER INSOLES

The hydraulic Water Wave™ membrane moves with your foot — water under pressure shifts precisely to where your foot exerts pressure. The foot arch therefore doesn't receive rigid immobilisation, but rather a dynamic response that gently engages the muscles with every step. For flat feet, this means the foot arch gradually strengthens through movement, not immobilisation.
