Flash Knit new waterproof knit material
After two years in Vancouver, Canada, a new waterproof knit called Flash Knit was developed to make the world's first 100% waterproof knit sneakers.
This fabric is breathable and water-tight and looks exactly the same as a regular knit fabric, but it keeps your shoes dry and clean no matter what the weather is.
For example, if you wear shoes made of this fabric on rainy days, you don't need to avoid any puddles. Rainwater and dirty water will not affect the shoes:
These little puddles are nothing, you can even step into the water!
In addition to the significant improvement in waterproof performance, it also made a more subversive change in breathability:
Unlike other waterproof shoes, this waterproof knit technology makes your feet skin more breathable, reducing sweat and odor.
This fabric called Flash Knit has three layers and is divided into different functional fabrics.
The first layer and the outermost layer are elastic braided layers, which are made of polyester fiber and nylon blended to provide waterproof, water-repellent and wind-proof effects. The second layer is a nano-filter layer that can further protect against water and moisture. The innermost layer is a breathable inner layer that helps the feet sweat.
