Sole Softec Ultra insoles provide a comfortable and custom experience for the user. The heat-moldable insoles are ideal for larger-fit footwear of all types (hiking boots and work boots included!). The Softec layer creates cushioning for the feet, while continuing to maintain a strong foundation for the foot. The feet feel balanced and aligned with the use of this product, and shock absorption is optimized.
Sizing based on shoe size. If you are a half size, it is recommended to go up a half size for all SOLE Footwear (if you normally wear an 8.5, choose a 9)
