Ultimate Performance Active Support Low Medium Arch Insole With F3D Large

Our Active models give a slightly lesser degree of support than the cushion and support versions of the Advanced insoles, and make a perfect foil to place in your everyday footwear; thus ensuring both 24/7 protection whatever you wear on your feet, and also a slight improvement in gait to help prevent repetitive strain injuries. These insoles are full length and replace the insoles in neutral or supportive running shoes: simply remove your existing insole, place over the top of the Advanced or Active insole, align the heel and trim around the toe to match. It is often advisable to wear them in gradually over the first couple of weeks to avoid muscle fatigue and to allow your body time to adapt to the improved gait and posture provided by the insole.
