The patented All-in-One Outsole system developed by our research
institute is a combination of the advantages of the existing
bulletproof midsole and the cushioning effect of the pyron midsole.
The “outsole + nailproof midsole (bulletproof midsole + pyron midsole)
+ insole” system has been made possible
(instead of the “outsole + pyron midsole + insole” system)
by reinforcing cushioning and dynamic stability and reducing thickness
to minimize worker fatigue. This system also prolongs the life span
of the shoes by ensuring that the outsole remains in the same position
regardless of changes in the shape of the shoes.

We took the insole, previously considered a mere shock-absorber,
to new heights and added features to minimize worker fatigue
and keep their feet healthy. The slip-resistance grip at the front of the
insole prevents the feet from sliding forward, while the minute holes
instantly absorb shock. The entire insole surface is applied with
tiny bumps to offer an acupressure treatment effect and covered with
anti-bacterial, anti-odor, and slip-resistant silver nano mesh fabric.
The air holes at the heel work to ensure ventilation and
disperse pressure evenly across the sole.
