TEMPUR® is known for their high-quality mattresses and pillows using the unique TEMPUR® formulation. The technology was originally developed by NASA, to absorb the g-force of astronauts during shuttle launches in the early 1970s. The TEMPUR® material has been perfected for pressure-relief and adapts to your body.  Nowadays, TEMPUR® has added the unique TEMPUR® material and comfort technology into each TEMPUR® insole. The shoe insert absorbs kinetic energy and releases pressure to provide comfort with each  step.
