Warm insoles More
WINTER WOOLSTEP are wool warm insoles for cold days.
The layer that comes into contact with the foot is made of wool, the middle layer is aluminium foil which insulates and thus prevents the penetration of cold and the bottom layer is made of latex to keep the insole in place. They are 5 mm thick, but only about 2.5 mm when stepped on.
Taking the insoles out after each wear and letting them dry will prolong their lifetime.
