The Swiss shoe manufacturer Joya develops and distributes back-friendly shoes. Joya enables a unique walking sensation and mimics the natural rolling movement. According to the AGR (Aktion Gesunder Rücken e. V.), all of Joya’s shoes are especially back-friendly and distinguished with the coveted AGR quality seal. The soft patented Joya sole ensures optimal pressure distribution under the sole of the foot. This prevents plantar stress concentrations. Joya causes the foot to sink in while stepping, which in turn causes the hip to drop down on that side. The muscles in the back must be stabilized by this movement, which can also have a positive effect on back problems. The strong cushioning effect of the soft PU sole reduces the pressure on the spine, which can provide a beneficial effect.
