* How to work RX footwear (rx1=back, rx2=knee, rx3=leg, and rx4=foot) :

RX footwear is engineered specifically to relieve foot, leg, knee, and back pain.
Its patented, shock-absorbing design greatly reduces impact to the body and distributes pressure more evenly across the foot than conventional shoes do. And less impact means less pain.

① Upper :
All RX uppers are well-constructed, using top-quality materials such as sandwich mesh , cowhide grain leather and tire rubber, for years of wear.

② RX®-orthotic :
RX® footwear is built upon a rigid RX®-orthotic foot cradle plate that supports and protects your entire mid-heel foot. By preventing over-stretching of the plantar ligaments across the base of the foot, this patented RX®-orthotic helps to prevent painful heel spurs and plantar fasciitis. It also serves to distribute impact pressure evenly across the bottom of the foot, reducing sore spots. Many of our customers report an improvement in their posture when they wear RX shoes as well.

③ Forefoot Cushioning, Flex Lines & Rocker Bottom :
The metatarsal bones at the ball of the foot are prone to injury from repetitive impact. RX® footwear protects your forefoot with nearly an inch of soft and resilient cushioning, and its rocker-bottom shape gently assists your forward motion.

Flex line is built into the shoe at the ball of the foot where the RX®-Orthotic plate ends, allowing your foot to bend naturally where it should and keeps the plantar ligaments from over-stretching. Contrary to popular belief, flexible shoes aren't what your feet need.

④ Conical Coil Spring :
The signature coil under the heel of RX footwear helps to protect your body from the damaging effects of impact, much like the shock-absorbers in a car.
As the coil compresses during heel-strike, it significantly slows the rate of impact experienced by the body. In fact, studies by Sandia National Laboratories in U.S.A. have shown that RX footwear provides 50% more cushioning than conventional shoes do.

An added benefit is energy return. The impact energy absorbed by the coil is stored as tension. As the foot moves forward, that tension is released, delivering 40-50% of your kinetic energy back to you. People who wear RX footwear often report that they feel less fatigue and have more energy at the end of the day.

④ RX® Heel (Coil Spring + Heel Pad) :
The heel can be easily replaceable and adjustable in a few minutes depending on customers' body weight, type of gait (walking style), type of illness, type of occupation, type of exercise, and other conditions. The heel has two types, open type of coil heel and enclosed type of coil heel. And each of them has more than 5 different coil sizes and tensions in order to customize. The open RX® heel can be adjusted by every 90 degree, and exchanged the left heel to the right heel and the other way to customize and fit, if needed.
