While most sports insoles are designed just to shield your feet from impacts, the G8 Performance Pro Series 2620 Insoles actively engage and stimulate more of your feet, building muscle and boosting energy efficiency. Not only can this elevate your athletic performance, it also reduces the stress on other parts of the body like your knees and back.
The 2620 Insoles have a highly customisable, adaptive design that lets you adjust the arch fit over time, so as your feet grow stronger, you can make the arch contact more dramatic for a clear sense of progression.
What's Included?
These G8 Insoles are supplied in four sizes that accommodate UK shoes sizes ranging from 4 to 13.5, which can be trimmed for a more precise fitting. To find your size, please consult the table below:
| G8 Insole Size | UK Shoe Size | Length x Width (mm) |
|---|---|---|
| Small | 4 - 6.5 | 260 x 93mm |
| Medium | 7 - 9 | 275 x 98mm |
| Large | 9.5 - 11 | 294 x 103mm |
| Extra Large | 12 - 13.5 | 310 x 114mm |
The G8 2620 Insoles are designed to gradually increase and eventually maximise the natural movement of the foot. Specifically, they aim to move your feet and engage the muscles as if you were barefoot, but with the added support and protection of insoles and shoes. In addition to increasing general comfort during exercise, they can also help in the following ways:
Strengthening your feet and exercising more of the muscles and tendons can help with a variety of workout-related issues in the feet and the rest of the body. This includes, but is not limited to:
As you can see above, each size of the G8 insoles is equivalent to a small range of UK sizes. To get the most beneficial insole size for you, you may have to trim the insoles. To do this correctly, please follow these steps:
Each set of Performance Series 2620 Insoles includes five different arch attachments, and you might understandably be wondering why. Well, while other insoles might mould to your feet, the 2620s aim to exercise your feet, structurally changing them and the way you move. In using the different arch attachments and settings as progression tools, you can strengthen your feet in much the same way as you would when increasing your lifting weight at the gym.
Instead of moving straight from one arch piece to the next, you gradually move each piece forward, and then eventually switch arch pieces.
Before we get into the arch adjustments of these insoles, it's important to get the initial fitting done right. It's a simple process with these steps:
The advice from G8 is to adjust or change the arch piece when it doesn't feel like it did yesterday:
In order for the G8 Insoles to do what they're made for, forward arch support positioning is key. When your feet land in a normal pair of insoles, the impact is between the forward arch and the shoes, and most of the foot remains unengaged, limiting blood flow and muscle stimulation.
Conversely, when an arch piece is fitted correctly to the 2620s, it flexes when your foot strikes the ground, encouraging the foot to splay and disperse force through the ball of the foot, for more even impact.
When more of the foot is engaged, more muscles and tendons are kicking off of the ground and absorbing impact. Not only does this make you more energy efficient, it also gives you better balance and helps reduce the impact on the parts of the body that generate force, like the hips and knees.
Yes, although 5 arch height pieces are provided, the maximum arch height is determined by your skeletal structure, along with muscular flexibility. For example, someone with a flat foot may only be able to a level 2 arch height, taken all the way forward, as level 3 would be too steep for their arches.
While you can make your foot more flexible, you cannot change skeletal structure. Each foot reacts and behaves differently, so experimentation with your own feet is key to finding the most beneficial fit.
As well as progression and muscle activation in the feet, the different arch supports and settings are great for accommodating injuries and other conditions. Also, as they can be adjusted independently, it's no problem if your left leg or foot is different to your right. Below are a few situations where the the ability to adjust your arch supports to your own feet could help:
Even if an injury or condition is temporary, one foot can use a more gentle arch setting, and be slowly trained until both feet match!
G8 have found that moving the arch pieces sideways has little to no effect on most people, with the exception of some cyclists. This is because a cyclist is strapped in, and so cannot adjust the angle of attack with the pedals like people can do while running. As such, cyclists may find it beneficial to experiment with the width settings of their insoles, just as we have advised everyone to do with the height settings.
While foot health and development are the main aims of the G8 Performance Insoles, your whole body can also feel huge benefits over time. Moving your feet in a more biomechanically correct way dispels the energy and impact, as well as reducing the energy that is returned back to where it is originally generated, like your knees, back, shins and hips. Stronger feet lessen stress on these more fragile body parts, reducing wear and encouraging healthier body alignment.
While most other athletic insoles on the market focus on shielding and protecting foot weakness while you exercise, the G8 2620 Insoles prioritise making your feet stronger. By engaging and activating more of your feet, the stress of exercise is better dispersed through the whole foot instead of just part of it. Over time, these issues will become much less severe and the parts of the foot that are protected by other insoles, can instead contribute to performance.
