Premium 3mm Orthotic Insoles for Running, Hiking & Sports - Arch Support & Cushioning for Comfort All Day (Rod/HOK/NEGON) - Ideal for Work, Gym & Outdoor Activities

Introducing our Full Grain Calf Insoles, crafted from premium full grain calf lining and padded with a 3mm memory foam layer for enhanced comfort. Designed to fit most of our boot lasts — including Rod, HOK and Negon — these insoles are perfect for fine-tuning the fit when between sizes or for replacing your Ultraflex insoles.

If between sizes, we recommend choosing the smaller size.
