NOTE: I will update this review to explain the long-term benefits of using these insoles.
Who Are Pro Series 2620 Insoles for?
G8 Performance Pro Series 2620 are customizable insoles suitable for riders who want to improve their comfort and performance.
Multiple arch piece sizes included in packing and possible positions make them suitable for flat, normal, and high arch feet.
They are designed in a way to actively exercise your feet which leads to a change in their shape. This also means you will have to adjust the arch pieces over time.
These insoles are recommended by many professional bike fitters worldwide and are considered one of the best cycling insoles.
In addition, you don’t have to limit yourself to their use in cycling shoes only. They are also suitable for other shoe types, including running shoes, ski boots, hiking boots, etc.
Pro Series 2620 Insoles Features & Benefits
Below is my summary of the main features of Pro Series 2620 and the resulting benefits.
- Available sizes: Small (EU 37-40), medium (EU 41-43), large (EU 44-46), extra-large (EU 47-49)
- Suitable for: Flat, normal, and high arch feet
- Weight: Around 112g / pair with arch pieces and metdomes (109g / pair without metdomes)
- Customizable: Yes (5 arch pieces, 11 positions)
- Trimmable: Yes
The G8 Performance Pro Series 2620 insoles are customizable. This means you can adjust their arch height and position using arch pieces.
The packing includes five pairs of arch pieces suitable for flat to high arch feet. The idea behind these insoles is that they allow your feet to move biomechanically correctly inside the shoes. Regular insoles inhibit all movement of the foot.
The movement inside the shoe leads to a change in the shape of your feet over time. So, you will have to adjust the position and height of the arch pieces as your feet change and get stronger.
You can use one of 11 positions to maximize your riding comfort and increase blood flow. G8 recommends combining the insoles with L1 or L2 metdomes.
The metdomes will spread the bones to increase the blood flow. So you should avoid tingling or numbness in your toes.
Another interesting feature is the non-slip surface which fixes your feet’ position in the shoe (and also allows adjusting the position of the metdomes).
Of course, you can trim the insoles to fit them into your cycling shoes.
My Experience with Pro Series 2620 Insoles
I’ve been using the Pro Series 2620 Insoles for about 3 months now.
Before them, I used my old custom orthotics (for flat arch feet) that are honestly not too comfortable when riding my bike. As a result, I experienced numbness during rides longer than 2-3 hours. The G8 insoles with metdomes solved this issue.
I had to trim them using scissors to fit them into my Fizik R5 Tempo Overcurve shoes, which are narrow (the G8 insoles are pretty wide).
It took me about 2-3 weeks to get used to them. Due to the anti-slip surface and new foot position, I sometimes almost got blisters. So, I recommend gradually building up your load to avoid this.
Rides out of the saddle now feel almost like riding with springs in shoes. Of course, the effect is not as strong, but the power transfer feels more effective.
G8 claims their insoles help you improve your performance, but it’s difficult to validate this claim. Yes, I push more watts than a few months ago, but this will be more likely thanks to the training.
It’s also important to say that these insoles are not omnipotent. If your bike doesn’t fit you due to its geometry, wrong saddle height, saddle position, etc., you should fix these issues first.
That’s why visiting a professional bike fitter is a good idea. You can consult him about other options.
David Lee from G8 Performance claims he experienced the biggest shift at around 18 months. I will continue using these insoles and update this review to share my long-term experience.
Pro Series 2620 Insoles FAQ
The Pro Series 2620 insoles are a great addition to my cycling kit. They improved my riding comfort, so I can now focus more on my performance and less on the foot discomfort.
I recommend using them with G8 Performance Metdomes, eventually custom heel wedges.
To maximize their potential, visit a professional bike fitter who should be able to help you with their fitting, eventually adjusting your riding position based on the changes in your feet position.
