About CSI Double Tab"Sprinter" Anatomic Left And Right

CSI Double Tab Sprinter: Anatomical Toes, compression fit, and engineered cushion in the foot bed. Anatomically shaped socks come specifically shaped for left and right feet, and are contoured to fit perfectly. Outlast technology, originally developed for NASA, utilizes phase change materials (PCM) that absorb, store and release heat for optimal thermal comfort.  Outlast technology is comparable to ice in a drink; as it changes from solid to liquid, it absorbs heat and cools the drink, keeping that drink at the desired temperature for longer. Outlast phase change materials work in the same way, but are microencapsulated to be permanently enclosed and protected in a polymer shell.
