Carhartt Insite Technology Footbed CMI9000 Insole - Comfortable & Supportive Shoe Insoles for Work Boots, Hiking & All-Day Wear

Insite engineered footbed. Cad designed footbed based on 120, 000 3D foot scan for fit, form and comfort. Ax suede top cover material provides 30 percent more grip to reduce foot slip. Foot slip creates heat and fatigue. Pulsion energy rebound foam top layer is engineered for maximum rebound to prevent fatigue during prolonged use. Single density pu foam bottom layer is specifically chosen for its compression set and ability to work with pulsion foam. Tetrapod technology design on the underside of the insole disperses compression in multiple direction while maintaining its shape.
