The core of Cestro is breathability
Breathability plays a crucial role in keeping your feet in optimal condition. Poor breathability can increase moisture buildup, leading to blisters and affecting not only foot health but also overall temperature regulation.
To enhance breathability, many brands incorporate mesh materials into their shoes. Mesh features thousands of tiny pores that allow air to circulate efficiently but also make it easier for water to seep in. To address this, membranes are often applied to shoes, providing waterproof protection but potentially compromising breathability.
The Importance of Breathable Footwear
A study of 142 experts from 18 countries found that 97% of participants ranked breathability as the most important shoe feature.
Shoe Feature | % Participants | Shoe Feature | % Participants |
---|---|---|---|
Shoe Mass | 100 | Toe Spring | 66/92 |
Upper Breathability | 97 | Heel Counter | 72 |
Forefoot Midsole Hardness | 93 | Medial Post | 72 |
Rearfoot Midsole Hardness | 93 | Midfoot Bending Stiffness | 72 |
Heel (stack) Height | 90 | Upper Elasticity | 72 |
Midsole Thickness | 86 | Insole Shape | 69 |
Forefoot Bending Stiffness | 83 | Lacing System | 68 |
Outsole Traction | 83 | Rocker | 59 |
Heel-to-Toe Drop | 79 | Heel Flares | 55 |
Torsional Bending Stiffness | 79 | Forefoot Flares | 45 |
Crash Pad | 76 |
Cestro, with an excellent breathability of 7ccs on average
Cestro offers more than 10 times the breathability compared to other membrane materials. Shoes made with Cestrol are so breathable that you can feel the air circulation as if an air conditioner is blowing inside.


Cestro has found the perfect balance between rainproofness and breathability
For daily shoes, you only need just above 1,000mmH2O to keep your feet dry in the most of the situations.
Shoes with a high level of waterproof rating can actually reduce breathability, making them stuffy and uncomfortable.
Rain Type | Required Waterproof Rating (mmH₂O) | Applicable Clothing |
---|---|---|
Drizzle | 50 | Normal Clothing |
Normal Rain | 100~300 | Golf Clothing |
Thick Rain | 500~1,000 | Ski Clothing |
Heavy Rain | 1,000~3,000 | Water Sports Clothing |
Rain Storm | Over 3,000 | Mountain Climbing Clothing |
Fitting test of Cestro applied shoes

A study was conducted with 10 runners wearing shoes equipped with common membranes, mesh materials, and shoes with Cestro. The experiment observed changes in humidity and temperature after walking for one hour.
Due to Cestro's maximized breathability, even after for an hour, it exhibited similar humidity and temperature levels as shoes with mesh materials.

Breathability Comparison Test for Shoes with Cestro Applied
10g of water was poured onto the sample, and the shoe dryer was activated. The weight was measured every 2 minutes, and the total weight change rate after 10 minutes was checked. After 30 minutes, the drying condition was checked.
- Cestro applied products decrease by 0.2g per measurement.
- General waterproof membrane decrease by 0.1g per measurement.
- After 30 minutes, Cestro showed a reduction of 4.73g, while the general waterproof membrane showed a reduction of 3.71g.

After 2 minutes | 338.92 ~ 0.2g | 342.33 |
After 4 minutes | 338.72 | 342.21 |
After 6 minutes | 338.56 ~ 0.2g | 342.10 |
After 8 minutes | 338.35 | 341.90 ~ 0.1g |
After 10 minutes | 338.16 | 340.66 |
After 30 minutes | 334.46 | 338.71 |
