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.
