ArFLEX
Comfortness with Flexibility
Shoe Insole SERIES

1. Shock/Pressure Absorbing of ArFLEX
During aerobic exercise/sport activities , the pressure given to feet is around 5 times of body weight . HWA CHING FOAM has recently developed the ArFLEX material , compare to regular PU foam ; it has very high resilience property which could absorb most of the pressure from body to feet . This minimizes the chance of feet injury during sports activities .
2. Comfortable Feet With ArFLEX
While regular walking or sports exercise , if shoe insoles are too hard or lack of resilience , it gives people impression that this pair of shoes is uncomfortable . Thus , a more comfortable material-ArFLEX , is recommended for shoe insole to match a pair of good shoes . ArFLEX foam has a much higher elongation value comparing to EVA ; when the foot bends during walking , it provides more comfort feeling .
3. Slim and Light Weight of ArFLEX
Due to the high resilience property of ArFLEX , only a very thin layer of it is required to provide same or better performance in supporting body weight . Unlike EVA shoe insole is normally 6mm to over 10mm , ArFLEX shoe insole could be as thin as 3mm and still comfortable . ArFLEX is a modern material/choice for shoe insole allowing designers more space and imagination in a pair of good shoes .
4. Anti-Bacteria of ArFLEX
In the ArFLEX formulation , we can choose to use anti-bacteria additives . This will prevent germs from growing in a pair of shoes, in some cases help to reduce odors .
5. Walking on Air with ArFLEX
The major difference between EVA and ArFLEX would be ‟air-flow” property. EVA has no air flow property at all, while ArFLEX foam is open cell foam allows air flow from top to bottom of the shoe insole .
6. Pressure resistance of ArFLEX
Compare to EVA , ArFLEX foam has a much lower value of ‟Compression Set” . This means that the shape of EVA shoe insole will change shape much easier and faster than ArFLEX shoe insole when pressure is given . ArFLEX shoe insole will extend the life time of a pair of good shoes .
