17650 Hytest Women’s Hy-Ground Hy-Light Static Dissipating Nano Toe Athletic Shoe. The 17650 is a responsive, comfortable, lightweight athletic shoe that protects like a work boot. Hytest has developed an extremely light, or Hy-Light, composite toe using nanotechnology that is as durable as regular comp toes, with more room for your feet and less weight in the front of your shoe, reducing fatigue. Additionally, Hytest has developed Hy-Ground technology that provides additional Static Dissipative protection in the shoe by wrapping the forefoot in conductive threading which creates more surface area to fight static buildup. The 17650 features a lightweight engineered mesh upper, abrasion resistant breathable mesh lining for added durability and comfort, a memory foam footbed, a lightweight EVA cushion midsole, a slip and oil resistant rubber outsole, and asymmetrical nano toe safety caps.
