Please refer to the video here on the 2620 fitting guide page.

You will need a new insole when your arch support is no longer
optimal and you have moved onto as high an arch as your foot allows.

The 2620 PRO SERIES orthotic insoles should last for the life of your shoe. (12-18 months).

Ignite heat moldable orthotic insoles will usually last 6-12 months.

Due to the amount of sweat -250ml per foot - combined with the heat and friction, the materials in your shoes and G8's will degrade and no longer function optimally.

There is also a hygiene factor.

The arch pieces can withstand a beating but after a while the spring in the arch piece will diminish.

Some people happen to wear their shoes out faster than others, so this is a factor as well.

The arch pieces will perform better when fitted under the forward arch and not near the rear near the heel.

Take care of your feet and they will take care of you.

New movement and biomechanics and better foot positioning with new G8’s can result in rubbing and blisters.

Make sure to wear them in slowly and you’ll find them comfortable in no time.

The G8 Performance 2620 PRO SERIES orthotic insoles may be customised to fit any athletic shoe, including sports shoes, ski boots, work boots, hiking boots, skates, medical or orthopaedic footwear.

They are not suitable for high heel shoes.

You can wear the same G8 orthotic insoles for different shoes (e.g. running shoes and cycling shoes) but be aware that it’s best to use the G8 insole specific to its application.

The many problems caused by flat feet is the main reason the 2620 orthotic insoles were developed!

G8 2620s are designed to encourage natural foot movement in the shoe and over time, the feet will become stronger and more effective at transferring force through the ball of the foot.

When feet are stronger and doing what they should, blood flow is increased (eliminating hot spots), nerve response is increased (providing better feedback to the brain), and increased force transfer to the place you need it most.

This force transfer also reduces energy return, which can help with calf and Achilles issues as well as knee problems.

Now, this is not an instant fix. Just like any other musculature system, the muscles take time to adapt and the rest of the body will follow suit.

If you begin with the level 1 arch piece in your shoes and adjust it
gradually as your feet build more strength.

The arch piece can be exchanged for a level 2 and eventually be moved forward. See the fitting guide for full details.

This is a gradual progression depending on how bad your feet are and can take between 8-18months.

You must listen to what your body is telling you which is the best indicator on how you need to graduate to the next level of arch or forward position.

Some plantar muscle pain may be experienced if you do high mileage in your 2620’s right out of the box.

You need to make sure you take the time to get used to the 2620s as the muscles and ligaments will need to adjust to the increased movement in your feet.

If you experience discomfort, allow your foot muscles to recover by resting them and applying topical magnesium.
