Today we're revealing the secret hidden ⚗️ in the Coolmax® fabric we use in the linings and insoles of our shoes! It's an especially breathable fabric that lets shoes breathe 😮💨, wicking sweat to the outside and keeping feet drier.
And so that little ones can understand the science, here's a super simple experiment 🧪. All you need is two T-shirts 👕 (one cotton and one made of Coolmax technical fabric, or a sports T-shirt) and some energy.

1️⃣ First, the cotton T-shirt. Time to get moving a bit: how about a few laps of the living room doing the 🐒 jumping monkey dance? You'll see the body warm up and start to sweat. That's exactly what we want!

2️⃣ Now repeat the test with the breathable technical T-shirt. Look together at how your little one feels and the state of the T-shirt 🤓.
The cotton one will probably get damp, feel heavier, and the body will feel hot and sticky. With Coolmax® technology, the T-shirt will be drier and your little one will feel fresh and light.
Why does this happen? The magic of Coolmax® lies in how the fabric is made: its fibres have tiny channels 🧬 that absorb sweat from the skin, draw it away from the body and carry it to the outer surface, where it evaporates on contact with the air. That way the body stays cool and dry.
Have you noticed that feet are never still? Even at rest, little toes move and sweat, and it's important for shoes to wick away some of that sweat. With the Coolmax lining and our breathable microfibre, sweat is channelled to the outside.
👁️🗨️ Even so, sweat from the insole tends to get trapped on the rubber sole, so we recommend taking the insoles out when you get home so they can dry overnight.
