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.
