  • Performance, comfort and support with foot-warming technologies
  • Reflective thermal barrier natural body heat is initially captured and retained by an ultra-thin foil layer
OUTLAST® Treated Top Cloth with Aegis®* Antimicrobial

  • Temperature phase change material (PCM) from OUTLAST® Technology along with a durable 100% polyester top cloth, interacts with the body’s temperature to absorb, store and release heat when needed
  • This technology, originally developed for NASA and USAF, works with body heat to stabilize temperature into a micro-climate that stays “not too hot, not too cold - just right”. Aegis®* 
  • Antimicrobial reduces odor

Heat-Circulation Technology

  • While running, heat is generated through energy
  • Air channels and a concave heel pad compress and expand, creating air circulation between the insole and the shoe, to help regulate the distribution of warm air within an enclosed shoe keeping the whole foot at a stable temperature by limiting hot and cold spots
  • During breaks in running, the air channels trap warmed air to provide additional insulation to regulate heat retention

Insulated EVA Base Material:

  • In combination with the technologies listed above, Spenco’s EVA base material provides excellent insulating characteristics while adding cushioning and support for lasting foot comfort
  • Walkers, runners and joggers seeking additional performance, comfort and support in a warm, “just right” environment
  • Lasting warmth and performance 
  • Increased shock absorption and heel strike protection
  • Reduced friction to help prevent blisters. Increased energy return for improved athletic performance
